15. ANS:
a
Butane is used as a domestic fuel because it readily undergoes combustion in oxygen to
produce a huge quantity of heat and energy.
b
Butane does not dissolve in water because water is a polar solvent, whereas butane is a
nonpolar molecule.
c
Butane is a non-polar molecule which has no charge, and therefore is not attracted toward
any ions or polar molecule. The carbon-to-carbon and carbon-to-hydrogen bonds in butane
are very strong. Hence, they are not broken easily.
