Problem
The formation of PH4+ is difficult compared with NH4+ because:
(1) The lone pair of phosphorus is optically inert.
(2) The lone pair of phosphorus resides in an almost pure p-orbital.
(3) The lone pair of phosphorus resides in an sp3 orbital.
(4) The lone pair of phosphorus resides in an almost pure s-orbital.
