Question

Among the following, the number of planar, polar species are:
$N{H}_3,Cl{F}_3,B{F}_3,HN{O}_3,S{F}_4,S{O}_2,Xe{F}_4,lC{l}_3\left(g\right)$

• A. $3$
• B. $4$
• C. $5$
• D. $6$

Answer 1

Answer: (B)

$4$

$Cl{F}_3$ and $IC{l}_3$ are $s{p}^{3}d$ hybridized but planar due to the presence of $2$ lp. It is T-shaped and polar.

$HN{O}_3$ and $S{O}_2$ are $s{p}^2$ hybridized and hence, is planar and polar due to the difference in electronegativity.

$B{F}_3$ and $S{O}_2$ is planar, $s{p}^2$ hybridized but non-polar due to symmetrical structure.

$N{H}_3$ is $s{p}^3$ hybridized, polar and non-planar.

$S{F}_4$ is $s{p}^{3}d$ hybridized, polar and nonplanar.

$Xe{F}_4$ is $s{p}^3{d}^2$ hybridized, polar and non-planar.
