Question

Among the following compounds the one that is polar and has central atom with $s{p}^3$ hybridisation is:

• A. $H_{2}C{O}_3$
• B. $Si{F}_4$
• C. $B{F}_3$
• D. $HCl{O}_2$

Answer 1

The correct option is D $HCl{O}_2$

$HCl{O}_2$ structure is $OH-Cl=O$ Central $Cl$ atom is surrounded with two different EN groups. Thus is polar and has $s{p}^3$ hybridization. $B{F}_3$ and $H_{2}C{O}_3$ are also polar but $s{p}^2$ hybridized. and $Si{F}_4$ is non polar.
