Question

Match the following

List-I (Molecule)	List-II (Dipole moment in D)
A) \( \text{HCCl} \)	I) \( 1.85 \, \text{D} \)
B) \( \text{NH}_3 \)	II) \( 1.07 \, \text{D} \)
C) \( \text{H}_2\text{O} \)	III) \( 0.23 \, \text{D} \)
D) \( \text{NF}_3 \)	IV) \( 1.47 \, \text{D} \)

• A. A-II, B-IV, C-I, D-III
• B. A-IV, B-III, C-I, D-II
• C. A-II, B-I, C-IV, D-I
• D. A-III, B-II, C-IV, D-I

Hint:

When studying dipole moments, remember that the value depends on the molecular geometry and electronegativity of the atoms involved.

Answer 1

The Correct Option is A

The correct matching is as follows:
- A) HCCl has a dipole moment of 1.85 D, so it matches with II.
- B) NH₃ has a dipole moment of 1.07 D, so it matches with IV.
- C) H₂O has a dipole moment of 1.47 D, so it matches with I.
- D) NF₃ has a dipole moment of 0.23 D, so it matches with III.
