Explanation:
Detailed explanation-1: -The homologous series of straight-chained alkanes begins methane (CH4), ethane (C2H6), propane (C3H8), butane (C4H10), and pentane (C5H12).
Detailed explanation-2: -The alkane having 4 carbon atoms is butane. It has isomers n butane and isobutane.
Detailed explanation-3: -The low-molecular mass alkanes, from 1 to 4 carbons, are frequently used as cooking fuels; molecules of intermediate length (6-12 carbons) are found in gasoline and diesel fuels; longer carbon chains are found in motor oils, lubricants, emollients, greases, waxes, paraffin, and other applications.
