Question

Which of the following has maximum p-character?

• A. ${Cl{O}_2}^{-}$
• B. $SnC{l}_2$
• C. $C{S}_2$
• D. None of the above

Answer 1

The correct option is A ${Cl{O}_2}^{-}$

$Cl{O}_2^{-}$ is $s{p}^3$ hybridized with $2$ bp and $2$ lp.

$SnC{l}_2$ is $s{p}^2$ hybridized with $2$ bp and $1$ lp.

$C{S}_2$ is sp hybridized with $2$ bp.

The maximum p-character is in $s{p}^3$ which is $\frac{3}{4}\times 100=75$%

Option A is correct.
