Cl is butyl chloride. It is water white liquid with a sharp odor. It has the highest boiling point that is 77−78

∘

C.(173

F)

Answer 2

Answer:

(d) CH3(CH2)3Cl

Explanation:

CH3(CH2)3Cl will have the maximum boiling point as the boiling point of alkyl halides increases with an increasing number of carbon atoms. This is due to an increase in the intermolecular forces as the number of carbon atoms and electrons increases.

CH3Cl has a boiling point of -24.2 °C

CH3CH2Cl has a boiling point of 12.3 °C

CH3(CH2)2Cl has a boiling point of 42.7 °C

CH3(CH2)3Cl has a boiling point of 77 °C
