Question

The correct order of hybridisation of the central atom in the following species $N{F}_3$,$B{F}_3$,$P{F}_5$,$[Si{F}_6{]}^{2-}$ is:

• A. $s{p}^2$, $s{p}^3$, $s{p}^3{d}^2$, $s{p}^{3}d$
• B. $s{p}^3$, $s{p}^2$, $s{p}^{3}d$, $s{p}^3{d}^2$
• C. $s{p}^2$, $s{p}^3$, $s{p}^{3}d$, $s{p}^3{d}^2$
• D. $s{p}^3,s{p}^2,s{p}^3{d}^2,s{p}^3{d}^3$

Answer 1

The correct option is B $s{p}^3$, $s{p}^2$, $s{p}^{3}d$, $s{p}^3{d}^2$

$N{F}_3$ is $s{p}^3$ hybridized with $3$ bp and $1$ lp,

$B{F}_3$ is $s{p}^2$ hybridized with $3$ bp,

$P{F}_5$ is $s{p}^{3}d$ hybridized with $5$ bp,

$[Si{F}_6{]}^{2-}$ is $s{p}^3{d}^2$ hybridized with $6$ bp.
