MCQ
Which of the following base is weakest
- A$N{H_4}OH:{K_b} = 1.6 \times {10^{ - 6}}$
- ✓${C_6}{H_5}N{H_2}:{K_b} = 3.8 \times {10^{ - 10}}$
- C${C_2}{H_5}N{H_2}:{K_b} = 5.6 \times {10^{ - 4}}$
- D${C_6}{H_7}N:{K_b} = 6.3 \times {10^{ - 10}}$
✓
Answer
Correct option: B.
${C_6}{H_5}N{H_2}:{K_b} = 3.8 \times {10^{ - 10}}$
(b) Smallest value of ${K_b}$ indicates that aniline $({C_2}{H_5}N{H_2})$ is the weakest base.
