Question

homologous series is a series of organic compounds which belong to the same family ie, possess same functional group) and show similar chemical properties The members of this series are called homologous and differ from each other by the number of CH, units in the main carbon chain The chemical properties of which of the following compounds is similar to the butane ? a) Butyne b) Propene c) Propyne d) Pentane 1 i) The difference between two consecutive members in a homologous series in alkanes in terms of molecular mass and number of atoms of elements is a) 14 a.m.u and CH, respectively b) 12 amu and CH, respectively c) 14 a.mu and CH, respectivelyd) 12 a.mu and CH, respectively ii) The compound CH,CH(OH)CH,belongs to which of the following homologous series? a) Aldehydes b) Alcohols c) Ketones d) Carboxylic acids 1 iv) Which of the following is not the property of a homologous series? a) They show similar chemical properties b) They differ by 14 units by mass c) They all contain double bond d) They can be represented by a general formula Which of the following represent the name and formula of the 2nd member of v) homologousseries having general formula C,H? a) Methane, CH, b) Ethane, C,H, c) Ethene, C.H, d) Ethyne (C.H,)​

Answer 1

Answer:

A homologous series is a family of compounds which have the same general formula (*) and have a similar molecular structure and similar chemical properties because they have the same functional group of atoms (e.g. C=C alkene, C-OH alcohol or -COOH carboxylic acid).
