In case of nitrogen, NCl_3 is possible but not NCl_5 while in case of phosphorous, PCl_3 as well as PCl_5 are possible. It is due to

JEE Main 2002 Chemistry question

In case of nitrogen, is possible but not while in case of phosphorous, as well as are possible. It is due to

(1)availability of vacant d orbitals in P but not in NCorrect
(2)lower electronegativity of P than N
(3)lower tendency of H - bond formation in P than N
(4)occurrence of P in solid while N in gaseous state at room temperature

Answer: (1)

Solution

To form five bonds, an atom must have five unpaired electrons. Phosphorus (3s²3p³) can promote a 3s electron into its vacant 3d orbitals ( hybridisation), allowing . Nitrogen (2s²2p³) has no d
