Question

Which of the following will be the strongest bond? (A) F — O  (B) O — Cl  (C) N — H  (D)  O — H

Tardigrade Admin · Accepted Answer

Bond strength is determined by the bond order Bond strength propto Electronegativity difference Let's see the EN difference one by one F - O =0.5 O - Cl =0.5 N - H =0.9 O - H =1.4

Q. Which of the following will be the strongest bond?

$F — O$

$O — Cl$

$N — H$

$O — H$

Bond strength is determined by the bond order Bond strength $\propto$ Electronegativity difference Let's see the EN difference one by one
$F - O = 0.5$
$O - Cl = 0.5$
$N - H = 0.9$
$O - H = 1.4$
