Question

Among the following compounds the one that is polar and has central atom with $s{p}^2$ hybridisation is:

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

Polar bond is formed when electronegative difference between bonded atoms is more than 1.7.
$In{H}_{2}C{O}_3–Ciss{p}^2$ hybridised and molecule is polar.In $B{F}_3,Biss{p}^2$ hybridised and molecule is non polar, in $Si{F}_4$
Si is $s{p}^3$ hybridised and molecule is non polar, in $HCl{O}_2,Cliss{p}^3$hybridised the ,the molecule is non polar
