Question

7. C3H6 , C4H8 , C5H10 belong to same

homologous series.

i) Arrange the hydrocarbons in order of increasing

boiling points.

ii) Why melting point and boiling point of C5H10

are higher than C4H8

iii) Write the names of the given compounds.​

Answer 1

Answer:

Hii dear

Explanation:

1. The order of bolling point is as :

petane, butane , propane

because due to long chain intermolecular forces increase and thus it is difficult to break them and thus Petane will have high B.P

2. I have already given this answer in the above question

Petane is a long chain compound.

3. the name of compound is as like : propane , butane and pantene

thank u

dear

Answer 2

Explanation:

The boiling point of the hydrocarbons increases with the increasing molecular mass.

As molecular mass increases the intermolecular force of attractions (Van der Waal's force and London force) increases that require a higher amount of energy to break the bond.

C6H6 < C4H8 < C5H10
