- A III \(>\) I \(>\) IV \(>\) II
- B IV \(>\) I \(>\) III \(>\) II
- C I \(>\) IV \(>\) II \(>\) III
- D III \(>\) II \(>\) I \(>\) IV
Answer & Solution
Correct Answer
(A) III \(>\) I \(>\) IV \(>\) II
Step-by-step Solution
Detailed explanation
Dipole moment is a vector quantity. It is defined as the product of the magnitude of the charge and the distance between the centres of the positive and negative charges. Dipole moment of \(\mathrm{NF}_3\) and \(\mathrm{NH}_3\) The dipole moment of \(\mathrm{NH}_3\) is larger…
