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`.

Options

A. `AsH_(3)`
B. `GeH_(3)`
C. `P_(4)`
D. `H_(2)Se`

Answer
