Assertion (A) : Dipole moment of o-dichloro benzene is larger than the theoretical value.
Reason (R): Due to dipole-dipole repulsion of two -atoms in ortho position bond angle is greater than .
Reason (R): Due to dipole-dipole repulsion of two -atoms in ortho position bond angle is greater than .
View answer and explanation
Correct option: D
is false but is true.
The correct answer is D ( is false but is true) because the dipole moment of o-dichlorobenzene is *smaller* than the theoretical value due to the vector addition of the bond dipoles, and the reason is correct that the bond angle is greater than 60 degrees due to repulsion.
