JEE Main 2025 Question Paper (22-Jan-2025) (Shift 2)

Question 1

Arrange the following compounds in increasing order of their dipole moment : $\mathrm{HBr}, \mathrm{H}_2\mathrm{S}, \mathrm{NF}_3, \mathrm{and} \mathrm{CHCl}_3$

Accepted Answer

${\mathrm{NF}}_{3} < \mathrm{HBr} < {\mathrm{H}}_{2}\mathrm{S} < {\mathrm{CHCl}}_{3}$

Answer

$ \mathrm{HBr} < \mathrm{H}_2\mathrm{S} < \mathrm{NF}_3 < \mathrm{CHCl}_3 $

Answer

${\mathrm{H}}_{2}\mathrm{S} < \mathrm{HBr} < {\mathrm{NF}}_{3} < {\mathrm{CHCl}}_{3}$

Answer

${\mathrm{CHCl}}_{3} < {\mathrm{NF}}_{3} < \mathrm{HBr} < {\mathrm{H}}_{2}\mathrm{S}$

Question 4

Consider the given figure and choose the correct option :

Accepted Answer

Activation energy of forward reaction is $ E_{1} + E_{2} $ and product is less stable than reactant.

Answer

Activation energy of backward reaction is $ E_{1} $ and product is more stable than reactant.

Answer

Activation energy of forward reaction is $E_{1} + E_{2}$ and product is more stable than reactant.

Answer

Activation energy of both forward and backward reaction is $ E_{1} + E_{2} $ and reactant is more stable than product.
