Question

the boiling point of pentane and hexane are 32 C and 69 C respectively. why? Although both are non polar molecules and contain same type of atoms

Answer 1

Answer:

due to difference in their masses

Explanation:

boiling point increases with increase in mass.

because when C atom is added the sigma bond is added which strengthen the bond

now it will require more energy to break the bond.

so the boiling point is higher

Answer 2

Answer: boiling temperature is propasnal to number of carbon in atom.

Explanation: the boiling point is increasing because hexane has more carbon so it have more vander Waals force so it is difficult to break than pentane .
