Question
Why does R3P = O exist but R3N = 0 does not (R = alkyl group)?
Solution
R3P = 0 exists but R2 N = 0 does not exist because N- due to the absence of d-orbitals cannot form multiple bond thus N- cannot expand its covalency beyond the 4.
On other hand P due to having d- oribital forms mutiple bonds and hence can expand covalency beyond 4.
thus R3P = 0 exists but R2 N = 0 does not exist.

thus R3P = 0 exists but R2 N = 0 does not exist.
