1.	(a) Define a homologous series. Give the name and structural formula of one homologue of the following : CH3OH (b) Write the molecular formula of the third member of the homologous series of carbon compounds with general formula CnH2n+1OH. (c) Name any two fossil fuels. Lakhmir Singh Chemistry Class 10
Answer» A) A homologous SERIES is a series in which each SUCCESSIVE member DIFFERS by a CH2 group.For CH3OH the next member of homologous series would be CH3CH2OH.B) It will be CH3CH2CH2OH.C) Coal and petroleum.Hope it help EXPLANATION:
