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.

Description : Out of pentane, 2-methylbutane and 2,2-dimethylpropane which has the highest boiling point and why?

Last Answer : Ans. Pentane having a continuous chain of five carbon atoms has the highest boiling point (309.1K) whereas 2,2 - dimethylpropane boils at 282.5K. With increase in number ... and therefore weak intermolecular forces between spherical molecules, which are overcome at relatively lower temperatures
