Question

Which of the following hybridization's has maximum s-character?

• A. ${sp}^3$
• B. ${sp}^2$
• C. $sp$
• D. All have same s-character

Answer 1

The correct option is C $sp$

s-character is the contribution of sigma type bond in a hybridization.

$s{p}^3=25$% s-character, $75$% p-character

$s{p}^2=33$% s-character, $67$% p-character

$sp=50$% s-character, $50$% p-character

The more s-character a bond has, the stronger and shorter the bond is. so an $sp-sp$ bond is strongest, and $s{p}^3-s{p}^3$ bond is weakest.
