by

1 Answer

Answer :

Methane is CH 4 next homologue is CH 4 + CH 2 = C 2 H 6 (Ethane)

Pentane is C 5 H 12 , next homologue is C 5 H 12 + CH 2 = C 6 H 14 (Hexane)

Is pentane an unsaturated hydrocarbon?

Description : Is pentane an unsaturated hydrocarbon?

Last Answer : No. It is saturated. The prefix pent- indicates that there are five carbon atoms, and the suffix -ane indicates that the carbon atoms are single-bonded. Therefore, the rest of the bonds ... hydrogen, so it is saturated with hydrogen. The chemical formula for pentane is C5H12, or CH3CH2CH2CH2CH3.

Description : (a) What effect the branching of an alkane has on its melting point? (L-III) (b) Which of the following has highest boiling point?(L-III) (1) 2-methyl pentane. (2) 2, 3-diethyl butane. (3) 2, 2- dimethyl butane.

Last Answer : Ans.(a) In general conception, as the branching increases packing of the molecules in the crystals becomes less close and have melting point decreases accordingly. (b) As the branching increases, ... attraction decreases and hence the boiling point decreases. So, 2-methyl pentane has highest B.pt.
