In which of the following does the first compound have a higher dipole moment than the second ?

Options

A.
B.
C.
D.

Answer

A, D

Explanation

`a.` In nitrobenzene, small angle so high dipole moment `(mu).`
`b.` `(` low `mu`, distance is less, due to double bond `)`
`[` High `mu`, more charge separate and large distance `(` single bond, more bond length `),` since `mu=qxxd(` charge `xx` distance `).]`
`c.`
`d.`
