Trimethyl amine oxide and trimethyl phos...

Trimethyl amine oxide and trimethyl phosphine oxide can be represented as
`(CH_3)_3N^(+)-O^(-) , (CH_3)_3P^(+)-O^(-)`
Answer the following questions based on these
Triphenyl Phosphine oxide can be respectively by two canonical forms but trimethyl amine oxide can't be
`(CH_3)_3P^(+) - O^(-) harr (CH_3)_(3)P=O`
It is due to

A

Phosphorus accepts charge density from oxygen and accomodates it in its vacant d - orbitals

B

Nitrogen does not posses d - orbitals and thus can't form the `pi` - bonded structure

C

Both (a) and (b)

D

None forms canonical forms
