Detailed explanation-1: -Assertion (A): Following are the members of a homologous series: CH3OH, CH3CH2OH, CH3CH2CH2OH Reason (R): A series of compounds with same functional group but differing by ––CH2 – unit is called a homologous series.
Detailed explanation-2: -Expert-Verified Answer CH3OH (methanol) is member of alcohol homologous series. Next member in this series is ethanol (C2H5OH) with structural formula CH3-CH2-OH. (b) Compounds with general formula CnH2n+1OH are called alcohols. 3rd member in alcohol series is propanol (C3H7-OH).
Detailed explanation-3: -Solution : Propanol and acetic acid.
Detailed explanation-4: -A series of organic compounds that contains the same functional group and in which the number of carbon atoms in each consecutive member differs by one is called a homologous series for that functional group. The series CH3Br, C2H5Br, and C3H7Br represents the first three members of the homologous series of bromides.
Detailed explanation-5: -Answer: c2h5oh and ch3cooh. Explanation: the homologous of ch3oh is c2h5oh and of hcooh is ch3cooh as the is a difference of ch2 in every higher homologous terms.
