Drago suggested an emprical rule which is compatible with the energetics of hybridization. It will occupy a stereochemically inactive s-orbital, and the bonding will be through p-orbitals and bond angles will be nearly 90^(@) if the electronegativity of the surrounding atoms is le2.5. Q.Correct order of bond angle is :
