Passage / Comprehension

Dipole moment is a vector sum of all the individual bond moments. Mathematically it is m = q × d, where q is magnitude of partial charges and d is the distance between centres of opposite charges.

Its main application includes, determination of polarity of bond, symmetry of molecule and in calculation of % ionic character.

The Dipole Moment produced in the molecule

is equal to μ , then for given molecules,correct options is/are :

Options:(select one or more)

Answer:
A, B, D
Solution:

Treat each C–F dipole = μ

Net dipole = vector sum

(I)Symmetric arrangement → partial cancellation

  • μ₁ = μ₄

(II) Least symmetry → maximum dipole

(III)More symmetric than II → intermediate

  • μ₃ = √3 μ

(IV)Symmetric like (I) → μ₁ = μ₄

Final order:

I = IV < III < II
