Among CH₃Cl, CH₃Br, CH₃I, the order of dipole moments is approximately:
ACH₃Cl > CH₃Br > CH₃I
BAll zero
CCH₃I > CH₃Br > CH₃Cl
DCH₃Br > CH₃Cl > CH₃I (values are 1.860, 1.830, 1.636 D — nearly equal but slight peak at Br/Cl)
Answer & Solution
Correct answer: A. CH₃Cl > CH₃Br > CH₃I
Dipole moments (per NCERT Table 6.2): CH₃F (1.847), CH₃Cl (1.860), CH₃Br (1.830), CH₃I (1.636). So roughly **CH₃Cl ≈ CH₃F > CH₃Br > CH₃I**. NEET often asks: among these, the **lowest dipole moment is CH₃I** (longest, least polar bond).
