Choose the correct answer from the options given below :
- A \((\mathrm{A})<(\mathrm{B})<(\mathrm{C})<(\mathrm{D})\)
- B \((\mathrm{B})<(\mathrm{C})<(\mathrm{C})<(\mathrm{D})\)
- C \((\mathrm{D})<(\mathrm{C})<(\mathrm{A})<(\mathrm{B})\)
- D \((\mathrm{B})<(\mathrm{A})<(\mathrm{D})<(\mathrm{C})\)
Answer & Solution
Correct Answer
(B) \((\mathrm{B})<(\mathrm{C})<(\mathrm{C})<(\mathrm{D})\)
Step-by-step Solution
Detailed explanation
Compounds having same number of carbon atoms follow the boiling point order as: (Boiling point \()_{\text {Hydogen bending }}>\) (Boiling point \()_{\text {iigh polarity }}>\) \((\text { Boiling point })_{1 \text { or polarity }}>(\text { Boiling point })_{\text {nou polar }}\)
