Which list does NOT contain compounds found in the same homologous series?
|
|
methane, ethane, propane, butane
|
|
|
Pentane, hexanol, heptane, octane
|
|
|
nonane, decane, undecane, dodecane
|
|
|

Explanation:
Detailed explanation-1: -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-2: -The homologous series of straight-chained alkanes begins methane (CH4), ethane (C2H6), propane (C3H8), butane (C4H10), and pentane (C5H12).
Detailed explanation-3: -A homologous series is a group of organic compounds in which the successive compounds usually differ by CH2. Hence, among the above, the hydrocarbons C3H6 and C4H8 belong to the same homologous series.
Detailed explanation-4: -So, 2-butyne does not form the member of homologous series.
