In which of the following compound, observed bond angle is found to be greater than expected, but no — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Due to 2p\pi-3d\pi back bonding observed bond angle in N(SiH3)3 and O(SiH3)2 is higher than expected. N(CH3)3 and O(CH3)2 both have no back bonding but higher bond angle is due to steric repulsions between methyl groups.
