The structures of some organic compounds are given. Identify the isomers among the structures given above. (b) State the members of the homologous series which are not isomers. (c) Write the I.U.P.A.C. name of C. Model Question Papaer 1, Concise Chemistry Solutions ICSE Class 10

(a) Identify the isomers among the structures given above.

(b) State the members of the homologous series which are not isomers.

(c) Write the I.U.P.A.C. name of C.

Answer

(a) A, B, and C are isomers of each other as they all have the molecular formula C4H8

(b) A, B and C are all alkenes with 4 carbon atoms (C4H8), D is an alkene with 5 carbon atoms (C5H10). Therefore, D(1-pentene) is a member of homologous series of alkenes but is not an isomer of A, B, or C.

(c) 2-Methylpropene
