The unbranched ( straight chain) alkanes possess

Explain why A branched chain alkane possesses lower boiling point than the corresponding straight chain alkane.

Assertion : Butane and 2- methyl butane are chain isomers. Reason : Butane is a straight chain alkane while 2- methyl butane is a branched chain alkane.

Assertion : Butane and isopentane are homologues. Reason : Butane is a straight chain atkane while isopentane is a branched chain alkane.

Out of a straight chain alkane and a straight chain alkene having the same number of carbon atoms, which has a higher octane number?

Give the structures and IUPAC names of straight chain alkanes with molecular formula C_(4)H_(10)
