Question

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

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

Answer 1

Answer: (A)

$H_{2}C{O}_3$

Carbon in $H_{2}C{O}_3$ has $s{p}^2$ - hybridization and is polar as individual bond dipoles do not cancel each other.

$B{F}_3$ has $s{p}^2$ - hybridized but is non-polar. $Si{F}_4$ has $s{p}^3$ - hybridization. $HCl{O}_2$ has $s{p}^3$ - hybridization.
