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$C{H_3}\mathop C\limits^ + HO$
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
