Question
In case of nitrogen, 
is possible but not 
while in case of phosphorus,
as well 
as are possible. It is due to
Lower electronegativity of P but not in N
Lower tendency of H bond formation in P than N
Availability of vacant -orbital in P but not in N
Occurrence of P in solid while N in gaseous state at room temperature
Lower electronegativity of P but not in N
Lower tendency of H bond formation in P than N
Availability of vacant -orbital in P but not in N
Occurrence of P in solid while N in gaseous state at room temperature
The correct answer is: Availability of vacant -orbital in P but not in N
Nitrogen does not have -orbitals
