Answer 1

(1)

Explanation:

HCl gas dissolves in water and also in organic solvents such as toluene. Therefore, the Assertion (A) is true.

HCl is a polar covalent compound because chlorine attracts the shared pair of electrons more strongly than hydrogen. Therefore, the Reason (R) is true.

Its polar nature accounts for its high solubility in water, while its covalent nature allows it to dissolve in organic solvents such as toluene. Therefore, the Reason correctly explains the Assertion.

Hence, both A and R are true, and R is the correct explanation of A.
