Which of the following bond has minimum bond energy?

Question

Which of the following bond has minimum bond energy? (A)  C-H  (B)  N-H  (C)  O-H  (D)  F-H

Tardigrade Admin · Accepted Answer

The bond between H and more electronegative element is more stable ie, its bond energy is maximum. Hence, the order of energy of bond formed between diatomic molecules should be as:

F H > O H > N H > C H

but the bond energy of N-H and C-H bond is comparable and the bond energy of N-H

(85 \approx 110)

is less than the bond energy of C-H bond

(90 \approx 110)
