Worked Solution & Example Answer:Which substances are members of the same homologous series? A - HSC - SSCE Chemistry - Question 1 - 2024 - Paper 1
Step 1
Identify the pairs of substances
Answer
Upon examining the given structures, we observe that the members of a homologous series must share the same general formula and only differ by a CH₂ unit.
In option A, the compounds are alcohols and alkanes, not from the same homologous series.
In option B, both compounds differ as one is an alcohol and the other is a hydrocarbon.
In option C, both are variations of alkanes, which do not share the same formula.
In option D, though one is an alkene, we notice the presence of a chlorine substituent, distinct from the others.
Thus, the correct answer is A as the pair closely resembles alcohol and alkane forms within a related structural framework.
