Boronsted-Lowry theory

Question

Statement 1 : ${CHCl}_{3}$ is more acidic than ${CHF}_{3}$ .
Statement 2 : The conjugate base of ${CHCl}_{3}$ is more stable than ${CHF}_{3}$

Moderate

A

Both Statement 1 and Statement 2 are true.
B

Statement 1 is true and statement 2 is false.
C

Statement 1 is false and Statement 2 is true.
D

Both Statement 1 and Statement 2 are false.

Solution

The conjugate base of ${CHCl}_{3}$ is more stable than conjugate base of ${CHF}_{3} (\bar{C} F_{3}) . \bar{C} {Cl}_{3}$ stabilized by -I effect of chlorine atoms as well as by the Resonance(or) back bonding. But conjugate base of ${CHF}_{3} (\bar{C} F_{3})$ is stabilized only by -I effect of fluorine atoms.
