Question

The total sum of number of $p π - d π$ bonds in the following molecules.
$S O_{3}, S O_{2}, X e O_{4}, I O_{3}^{-}$

Open in App

Solution

For $S O_{3}$ :

It is $s p^{2}$ hybridized and three electrons are involved in $π$ bonding out of which two are involved in $p π - d π$ bonds.
For $S O_{2}$ :

It is $s p^{2}$ hybridized and two electrons are involved in $π$ bonding out of which one is involved in $p π - d π$ bonds.
For $X e O_{4}$ :

It is $s p^{3}$ hybridized and 4 electrons are involved in $p π - d π$ bonds.
For $I O_{3}^{-}$ :

It is $s p^{3}$ hybridized and three electrons are involved in $p π - d π$ bonds.
$∴$ Sum of all the $p π - d π$ bonds $= 2 + 1 + 4 + 3 = 10$
