Question

Which one of the following is not correct order of boiling points of the alkyl/aryl halides?

• A. $CHCl_{3} > CH_{2}Cl_{2}$
• B. $CH_{3}(CH_{2})_{3}Cl > CH_{3} ⥂ (CH_{2})_{2}Cl$
• C. $(CH_{3})_{3}CCl > (CH_{3})_{2}CHCH_{2}Cl$
• D. $CH_{3}(CH_{2})_{3}Cl > CH_{3}CH_{2}CHClCH_{3}$

Answer 1

Answer: (C)

$(CH_{3})_{3}CCl > (CH_{3})_{2}CHCH_{2}Cl$

Answer 2

$(CH_{3})_{3}CCl > (CH_{3})_{2}CHCH_{2}Cl$is not correct as boiling points of $(CH_{3})_{3}CCl$is smaller than $(CH_{3})_{2}CHCH_{2}Cl.$ it is due to large surface area and shorter alkyl chain.

($(CH_{3})_{3}CCl > (CH_{3})_{2}CHCH_{2}Cl$
