Which one of the following has the highest dipole moment ?(i) CH_(2)Cl_(2)(ii) CHCl_(3)(iii) C Cl_(4)

Answer»

Solution :(i)
In `CH_(2)Cl_(2)`, the RESULTANT of two C - Cl bond moments are enhanced by resultant of two C - H bond moments.
(II)
In `CHCl_(3)`, the resultant of two C - Cl bond moments is opposed by the third C - Cl bond moment.
(iii) `C Cl_(4)` is symmetrical and bond moments are cancelled mutually.

Thus, ORDER of dipole moment is
`CH_(2)Cl_(2)GT CHCl_(3)gt C Cl_(4)` (non - polar).
