Question

Assertion : `CHCl_(3)` is more acidic than `CHF_(3)`.
Reason : The conjugate base of `CHCl_(3)` is more stable than `CHF_(3)`.
A. If both assertion and reason are true and reason is the correct explanation of the assertion
B. If both assertion and reason are true but reason is not the correct explanation is true but reason is false.
C. If the assertion and reason both are false.
D. If the assertion and reason both are false.

Answer 1

Correct Answer - A
The conjugate base of `CHCl_(3)` is more stable than conjugate base of `CHF_(3)(CF_(3))`. `C Cl_(3)` stabilized by -I effect of chlorine atoms as well as by the electrons. But conjugate base of `CF_(3)` is is stabilized only by -I effect of flourine atoms. Here both assertion and reason are true and reason is correct explanation of assertion.
