Question

For which of the following hybridizations is the bond angle minimum?

• A. $s{p}^2$
• B. $sp$
• C. $s{p}^3$
• D. All of the above have same bond angle.

Answer 1

The correct option is C $s{p}^3$

$\begin{array}{ccc}\text{Type of}& \text{No. of}& \text{Bond angle}\\ \text{hybridisation}& \text{hybrid}& \\ & \text{orbitals}& \\ & \text{obtained}& \\ sp& 2& {180}^{\circ }\\ s{p}^2& 3& {120}^{\circ }\\ s{p}^3& 4& {109}^{\circ }{28}^{{}^{\prime }}\end{array}$
(c) $s{p}^3-$ hybridization leads to bond angle of ${109}^{\circ }{28}^{{}^{\prime }}$ and is minimum.
