cimpare these with there general formula

as:-

ALKANE:

Answer 2

i) No one among them is derived from alkane as C12H29-COOH is not possible

ii) ALKENE

C15H29-COOH as alkyl branch ( C15H30 ) is of the form CnH2n i.e. general form of alkene

iii)ALKYNE

C16H29-COOH as alkyl branch ( C16H30 ) is of form CnH2n-2 i.e. general form of alkyne
