MCQ
The species in which the central atom uses $s{p^2}$ hybrid orbitals in its bonding is
  • A
    $P{H_3}$
  • B
    $N{H_3}$
  • ${H_3}{C^ + }$
  • D
    $Sb{H_3}$

Answer

Correct option: C.
${H_3}{C^ + }$
c
In $CH _3^{+}$the carbon atom is $sp ^2$ as it contains three bond pairs and zero lone pairs of electrons.

In ammonia $\left( NH _3\right.$ ), $N$ atom is $sp ^3$ ($3$ bond pairs and $1$ lone pair) hybridized whereas in others, pure $p$ orbitals are used.
