|
|
Same general formula
|
|
|
Similar chemical properties, i.e. undergo the same reactions
|
|
|
Varying physical properties, i.e. change in a predictable way
|
|
|
Different functional group
|
Detailed explanation-1: -A. All members are represented by the same genral formula. B. All members have same chemical properties. C. All members have same physical properties. All members have same functional group. Answer. C is wrong because all members of a homologous series show gradation in physical properties. 27-Jun-2022
Detailed explanation-2: -Chemical properties remain the same because of the presence of the same functional group. (a) Change in chemical properties-This is not observed in a homologous series. The chemical properties of all compounds in a homologous series remain the same.
Detailed explanation-3: -A homologous series is a series of compounds with the same general formula, usually varying by a CH2 group. In the given list of compounds methane, ethane and propane belong to the same homologous series of compounds and butene does not.
Detailed explanation-4: -False: In homologous series, there is a gradual change in the physical properties from member to member.
Detailed explanation-5: -The members of the homologous series have same functional group. Members have the same general formula. Members have the almost same chemical properties due to same functional group. Members have common general method of preparation. 05-Sept-2022
