Question

Rank the indicated bonds in each compounds in order of increasing bond strength:

• A. 1 < 2 < 3
• B. 3 < 1 < 2
• C. 1 < 3 < 2
• D. 2 < 3 < 1

Answer 1

The correct option is C 1 < 3 < 2

Solution:- (C) $1<3<2$

From the given fig., bond $\left(1\right)$ is formed by $s{p}^3$ hybridisation, bond $\left(2\right)$ is formed by $sp$ hybridisation and bond $\left(3\right)$ is formed by $s{p}^2$ hybridisation.

As we know that if the $\%$ of $s$-character increases then the bond strength gets increased.

Therefore, the increasing order of bond strength is-

$1<3<2$
