O B. It has a higher boiling point because each additional carbon in the chain adds strength to the -OH attraction to other -OH groups. 13 Solution Question 4. The correct answer is option B Actual boiling point of Hexanol = 157 o C Actual boiling point of ethanol = 78.37 o C The intermolecular forces in hexanol and ethanol is i.e., Hydrogen Bonding and since both molecules have single -OH group means equal inter moleculer forces. This eleminates option A. The boiling point increases with increase in molecular weight. This is the general reason for higher boiling point which is explained more deeply in option B which is the correct option .

1. O B. It has a higher boiling point because each additional carbon in the chain adds strength to the
-OH attraction to other -OH groups. 13
Solution
Question 4. The correct answer is option B
Actual boiling point of Hexanol = 157 o
C
Actual boiling point of ethanol = 78.37 o
C
The intermolecular forces in hexanol and ethanol is i.e., Hydrogen Bonding and since both
molecules have single -OH group means equal inter moleculer forces. This eleminates option A.
The boiling point increases with increase in molecular weight. This is the general reason for
higher boiling point which is explained more deeply in option B which is the correct option
