JEE Main 2026 Chemistry Sample Questions

We have given some questions from the Physics sample paper for reference. Here you can check the JEE Main 2026 Physics sample paper with answer key:

1. Identify the correct statement among the following:

Option 1: All naturally occurring amino acids except glycine contain one chiral centre. Option 2: All naturally occurring amino acids are optically active.

Option 3: Glutamic acid is the only amino acid that contains a –COOH group at the side chain.

Option 4: Amino acid cysteine easily undergoes dimerization due to the presence of free SH group.

Correct Answer: Amino acid, cysteine easily undergo dimerization due to the presence of free SH group.

Solution: * Isoleucine has 2 chiral centre

* Glycine is optically inactive

* Aspartic acid also contains COOH groups at the side chain.

* Cysteine easily dimmerise due to free SH gro

2. Consider the following molecules :

The correct order of rate of hydrolysis is

Option 1: r >q>p>s

Option 2: q >p>r>s 41

Option 3: p >r>q>s

Option 4: p >q>r>s Correct

Answer: p >q>r>s

Solution: Rate of hydrolysis ∝ Leaving group ability

Hence, the correct answer is option (4).

3. A solution is made by mixing one mole of volatile liquid A with 3 moles of volatile liquid B. The vapour pressure of pure A is 200 mm Hg and that of the solution is 500 mm Hg. The vapour pressure of pure B and the least volatile component of the solution, respectively, are :

Option 1: 1400 mm Hg, A

Option 2: 1400 mm Hg, B

Option 3: 600 mm Hg, B

Option 4: 600 mm Hg, A

Correct Answer: 600 mm Hg, A

Solution:

$

\begin{aligned}

&\begin{aligned}

& P_S=P_A^{\circ} \cdot X_A+P_B^{\circ} \cdot X_B \

& 500=200 \times \frac{1}{4}+P_B^{\circ} \cdot \frac{3}{4} \

& P_B^{\circ}=600 \mathrm{mmHg}

\end{aligned}\

&\text { As } \mathrm{P}_{\mathrm{A}}^{\mathrm{o}}<\mathrm{P}_{\mathrm{B}}^0 \Rightarrow \mathrm{~A} \text { is least volatile. }

\end{aligned}

$

Hence, the correct answer is option (4).

4. The property/properties that show irregularity in first four elements of group-17 is/are :

(A) Covalent radius

(B) Electron affinity

(C) Ionic radius

(D) First ionization energy

Choose the correct answer from the options given below:

Option 1: B and D only

Option 2: A and C only

Option 3: B only

Option 4: A, B, C and D

Correct Answer: B only

Solution: The order of first four elements of group-17 are as follows

F< Cl< Br< I (Covalent radius)

Cl > F>Br>I (Electron affinity)

$

\mathrm{F}^{-}<\mathrm{Cl}^{-}<\mathrm{Br}^{-}<\mathrm{I}^{-}

$

F >Cl>Br>I ( Ist ionization energy)

Electron affinity order is irregular. Hence, the correct answer is option (3).
