✓

Answer

Correct option: B.
$(\mathrm{B})<(\mathrm{C})<(\mathrm{C})<(\mathrm{D})$
b
Compounds having same number of carbon atoms follow the boiling point order as:

(Boiling point $)_{\text {Hydogen bending }}>$ (Boiling point $)_{\text {iigh polarity }}>$ $(\text { Boiling point })_{1 \text { or polarity }}>(\text { Boiling point })_{\text {nou polar }}$
