Chemistry is considered one of the easiest and most scoring subjects in NEET. Some of the scoring sections from NEET Chemistry Syllabus are Chemical Bonding, p-block, Coordination Compounds, etc. Candidates can also expect around 3-4 direct questions in NEET from these topics.
In this article below, sample topic-wise MCQ questions are provided so that the students can get a better idea of the type of questions asked in the NEET from chemistry.
For a better preparation plan of NEET Chemistry candidates can also divide the syllabus into 3 parts i.e. Physical, Organic, and Inorganic Chemistry. The difficulty level of questions of these 3 parts in the last year was:
Section/Difficulty Level | Number of Easy Questions | Number of Moderate Questions | Number of Difficult Questions |
---|---|---|---|
Organic | 8 | 3 | 1 |
Inorganic | 11 | 5 | 0 |
Physical | 8 | 5 | 4 |

Ques: Which among the following species is not paramagnetic?
Correct Option: A
Solution: Paramagnetism is a form of magnetism where some materials are weakly attracted by the externally applied magnetic fields and thus form an internal and induced magnetic field in the direction of the applied magnetic field. Cl- is diamagnetic.
Ques: Ozone is present in which among the layer of the atmosphere?
Correct Option; B
Solution: Ozone is present in the stratosphere layer of the atmosphere about 15 to 30 km above the Earth's surface.
Ques: Which among the following is the correct chronological order of atomic models?
Codes:
Correct Option: C
Solution: The correct chronological order of atomic models is as follows: Thomson’s, Rutherford’s, and Bohr’s atomic models.
Ques: On which among the following does the orientation of atomic orbitals depend?
Correct Option: C
Solution: The orientation of atomic orbitals depends on their magnetic quantum number.
Ques: The element with the atomic number 35 belongs to which among the following blocks?
Correct Option: C
Solution: The electronic configuration of elements with atomic numbers is 35 and therefore, it belongs to the p-block.
Ques: Which among the following blocks do the representative elements belong to?
Correct Option: B
Solution: Representative elements are those elements where all inner shells are complete but outer shells are incomplete. Therefore, they belong to s and p-block.
Ques: Which among the following aqueous solution is the best conductor of electricity?
Correct Option: A
Solution: HCl, the aqueous solution is the best conductor of electricity.
Ques: When we increase the concentration of reactants in reversible reactions then, what will happen to the equilibrium constant?
Correct Option: C
Solution: When we increase the concentration of reactants in a reversible reaction then, the equilibrium constant will remain unchanged.

Correct Option: C
Solution: At absolute zero, the entropy of a perfect crystal is zero according to the Third Law of Thermodynamics.
Ques: In which of the given circumstances does entropy decrease?
Correct Option: A
Solution: During the crystallization of sucrose from the solution, the entropy decreases.
Ques: An example of the adsorption process is?
Correct Option: C
Solution: An example of an adsorption process is silica gel in contact with water vapor.
Ques: Which among the following is referred to as the process of separating a crystalloid from a colloid by filtration?
Correct Option: A
Solution: Dialysis is known as the process of separating a crystalloid from a colloid by filtration.
Ques: Which among the following is the IUPAC name of Cryolite?
Correct Option: D
Solution: Cryolite is an ore of sodium and its IUPAC name is Sodium hexafluoroaluminate.
Ques: Which among the following does the chemical process in the production of steel from haematite ore involve?
Correct Option: C
Solution: The chemical processes in the production of steel from the haematite ore involve oxidation of C to Co2 and then reduction process.
Ques: Why do Zinc and mercury don’t show variable valency like d-block elements?
Correct Option: C
Solution: The main reason why zinc and mercury don’t show any variable valency unlike d-block elements is that their d-shells are complete.
Ques: Why does silver nitrate produce a black stain on the skin?
Correct option: C
Solution: Silver nitrate produces a black stain on the skin because of its reduction to metallic silver.
Ques: Which among the following has magnesium?
Correct Option: A
Solution: Chlorophyll is the magnesium porphyrin complex and it has magnesium at the center of the modified porphyrin ring septeon.
Ques: Trunbull’s blue is a compound of which among the following?
Correct Option: C
Solution: Trunbull’s blue is a compound of Ferrous Ferricyanide.
Ques: Which among the following can be prepared by using a Fitting reaction?
Correct Option: B
Solution: Diphenyl can be prepared by using the Fitting reaction.
Ques: The Grignard reagent is made by reacting magnesium with which among the following?
Correct Option: A
Solution: The Grignard reagent is made by reacting magnesium with Ethyl iodide.
Solution: The dehydration of alcohol is an example of which among the following reaction?
Correct Option: C
Solution: An elimination reaction example is dehydration of alcohol.
Ques: Which among the following is formed when tertiary butyl alcohol is passed over heated copper at 300 degrees Celsius?
Correct Option: C
Solution: When tertiary butyl alcohol is passed over heated copper at 300 degrees Celsius, then 2-methylpropene is formed.
Must Read:
Ques: Which among the following reaction is called the oxidation of toluene to benzaldehyde by chromyl chloride?
Correct Option; Etard reaction
Solution: Etard reaction is referred to as the oxidation of toluene to benzaldehyde by chromyl chloride.
Ques: Which among the following is an example of the addition of HCN to carbonyl compounds?
Correct option: C
Solution: Nucleophilic addition example is the addition of HCN to carbonyl compounds.
Ques: When an aldehyde reacts with a primary amine, it forms which among the following?
Correct Option: Schiff’s base
Solution: The Schiff’s base is formed when aldehyde reacts with a primary amine. It is used as pigments, catalysts, polymer stabilizers, and dyes, etc.
Ques: Which among the following is more basic than aniline?
Correct Option: C
Solution: Benzylamine compound is more basic when compared to aniline.
Ques: Which among the following is a reducing sugar?
Correct Option: Galactose
Solution: Reducing sugar is defined as any sugar that is capable of acting as a reducing agent due to the presence of free aldehyde or ketone group. All monosaccharides such as glucose, fructose, ribose are reducing sugars.
Ques: Who among the following coined the term enzyme?
Correct option: A
Solution: Wilhelm Kuhne coined the term enzyme in 1877.
Ques: What is the reason for not using fatty acid containing less than eight carbon atoms in the preparation of a soap?
Correct Option: D
Solution: Soap possesses a carboxylic acid chain through which hydrocarbons and sodium-potassium ions are attached and therefore, it has a tadpole-like structure. Though ions dissolve in water and non-ionic carbon chain dissolves in oil to form an emulsion. It is required that a non-ionic chain must have more than 8 carbon atoms to form an emulsion.
Ques: What is the surface tension of water when soap and detergent are added to water?
Correct Option: B
Solution: When soap and detergent are both added to the water, then the ionic part of them attracts grease and repels water molecules. Therefore, hydrogen bonds that hold water molecules become weak and the surface tension of soap and detergent is reduced.
Ques: What is the main cause of acidity in the stomach?
Correct Option: A
Solution: The release of extra gastric acids decrease pH level and causes acidity in the stomach.
