Correct statement (s) about dipole moment of `R_(3)NO and R_(3)PO` is /are:

Options

A. dipole moment of `R_(3)NOgt` dipole moment of `R_(3)PO`
B. dipole moment of `R_(3)NOlt` dipole moment of `R_(3)PO`
C. Experimental dipole moment of `R_(3)NOgt` Experimantal dipole moment of `R_(3)PO`
D. Experimental dipole moment of `R_(3)NOlt` Experimantal dipole moment of `R_(3)PO`

Answer

A, D

Explanation

`mu_(1)gtmu_(2)implies`due to higher difference in electronegativity of N and C than between P and C.
`mu_(1)gtmu_(2)implies` because `2p_(pi)-3d_(pi)` back bonding in the `P-O` bond decrease moment hence `(R_(3)NO)_(mu)gt(R_(3)PO)_(mu)`

Hence, experimental dipole moment of `R_(3)POlt`theoretical dipole moment of `R_(3)PO.`
