(B) Bromoform \(\left( CHBr _3\right)\)
(C) Chloromethane \(\left( CH _3 Cl \right)\)
(D) Dibromomethane \(\left( CH _2 Br _2\right)\)
Choose the correct answer from the options given below:
- A (A), (C), (D), (B)
- B (C), (A), (D), (B)
- C (C), (A), (B), (D)
- D (C), (B), (A), (D)
Answer & Solution
Correct Answer
(B) (C), (A), (D), (B)
Step-by-step Solution
Detailed explanation
Boiling points increase with increasing molecular weight due to stronger London dispersion forces. Molecular weights: \(CH_3Cl \(50.5 Increasing order of boiling points: (C), (A), (D), (B)
