Question

The species in which the central atom uses ${sp}^2$ - hybrid orbitals in its bonding is

• A. $P{H}_3$
• B. $N{H}_3$
• C. ${C{H}_3}^{+}$
• D. $Sb{H}_3$

Answer 1

The correct option is C

${C{H}_3}^{+}$

${C{H}_3}^{+}$

C is central atom

ep = $\frac{V+L+A-C}{2}$ = $\frac{4+3-1}{2}$ = 3

3 $\Rightarrow$ Trigonal Planar $\Rightarrow$ ${sp}^2$ hybridization.
