Question

Order of arrangement of the following compounds with increasing dipole moment is?

• A. (i) $<$ (iv) $<$ (ii) $<$ (iii)
• B. (iv) $<$ (i) $<$ (ii) $<$ (iii)
• C. (iv) $<$ (i) $<$ (iii) $<$ (ii)
• D. (iv) $<$ (ii) $<$ (i) $<$ (iii)

Answer 1

The correct option is B (iv) $<$ (i) $<$ (ii) $<$ (iii)

Toluene has higher dipole moment than p-chlorobenzene and lower than o-chlorobenzene and m-chlorobenzene.
Hence the correct order is-
(iv) < (i) < (ii) < (iii)
