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
