$CH_2=CH-CH_2-CH_3$ and $CH_3-CH=CH-CH_3$ (Geometrical isomer)

Vedclass · Answer

(C) In option $(A)$,$3$-methylanisole and ethoxybenzene are metamers because the alkyl group attached to the oxygen atom changes. In option $(B)$,$1,1$-dimethylcyclopropane and $1,2$-dimethylcyclopropane are position isomers,not chain isomers. In option $(C)$,$CH_2=CH-CH_2-CH_3$ (but-$1$-ene) and $CH_3-CH=CH-CH_3$ (but-$2$-ene) are position isomers,not geometrical isomers. In option $(D)$,$CH_2=CH-CH_2-CH_3$ (but-$1$-ene) and $CH_2=C(CH_3)-CH_3$ ($2$-methylprop-$1$-ene) are chain isomers. Since the question asks for the incorrect match and both $(B)$ and $(C)$ are technically incorrect,in standard competitive contexts,$(C)$ is often cited as the primary error regarding isomer classification. However,given the provided options,$(C)$ is the most clearly incorrect classification.
