Question

Among following transformations, the hybridization of the central atom remains unchanged in

• A. $C{O}_2\to HCOOH$
• B. $B{F}_3\to B{F}_4^{-}$
• C. $N{H}_3\to N{H}_4^{+}$
• D. $PC{l}_3\to PC{l}_5$

Answer 1

The correct option is C $N{H}_3\to N{H}_4^{+}$

The hybridization of the central atoms are as given below-
$C{O}_2\to HCOOH$
sp $s{p}^2$

$B{F}_3\to B{F}_4^{-}$
$s{p}^2$ $s{p}^3$

$N{H}_3\to N{H}_4^{+}$
$s{p}^3$ $s{p}^3$

$PC{l}_3\to PC{l}_5$
$s{p}^3$ $s{p}^{3}d$
