MCQ
The compound in which ${C^*}$ uses $s{p^3}$ hybrids for bond formation is
  • A
    $H\mathop C\limits^ + OOH$
  • B
    ${(N{H_2})_2}\mathop C\limits^ + O$
  • ${(N{H_3})_3}\mathop C\limits^ + OH$$HgC{l_2}$
  • D
    $C{H_3}\mathop C\limits^ + HO$

Answer

Correct option: C.
${(N{H_3})_3}\mathop C\limits^ + OH$$HgC{l_2}$
c
$\left( NH _3\right)_3 C^*OH HgCl _2$ in this molecule the $C ^*$ has to have all single bonds, therefore, it is $sp ^3$ hybridized.

Where as in $HC^*OOH,\left( NH _2\right)_2{ }C^*O$ and $CH _3 C^*HO$ in that all ${ }_{ C }^*$ having double bonds so the are showing $sp^2$ hybridization
