The first member of alkyne homologous series is: A. ethyne B. ethane C.propyne D.methane. A homologous series is a family of organic compounds which follows a regular structural pattern, in which each successive member differs in its molecular formula by a âCH 2 â group.. Other homologous series include the alkenes, C n H 2n, the alkanols, C n H 2n+1 OH, and the carboxylic acids, C n H 2n+1 COOH. Name the following : 1) second member of alkene series. The organisation of organic compounds into the various different homologous series makes the study of organic chemistry more systematic, orderly and effective. 3. A series of compounds in which successive members differ from one another by a CH 2 unit is called a homologous series. A type of formula that represents the composition of any member of an homologous series. The first member of alkyne homologous series is. Question bank for SSC. Browse by Stream ...

Characteristics of homologous series: All the members of the homologous series have same functional groups and hence similar chemical properties. The IUPAC name of the product of reaction of ethylene with hydrogen bromide, [ethyl bromide / bromoethane / dibromoethane] 4. For example, methane, ethane, propane, butane, etc. are solved by group of students and teacher of SSC, which is also the largest student community of SSC. Order in Homologous Series Photograph shows the first members of various homologous series. The First member of homologous series of alkene is. The incremental change in relative molecular mass is therefore fourteen. The first member of alkyne homologous series is. Files are available under licenses specified on their description page.
