Question

The shape of $C{H}_3^{+}$ is _____ (planar/bent).

Answer 1

$C$ has $4$ valence electrons. But in $C{H}_3$, , a positive charge makes the number of available electrons $3$.

It forms $3$ single bonds with $H$ to form a planar structure with $s{p}^2$ hybridization.

Hence, the correct answer is planar.
