Quizplus · Accepted Answer

The longest carbon chain is 5 carbons long, and it contains a methyl ether substituent at carbon 1. This substance is named as 1-methoxy-3-methylbutane. Choice A is incorrect because it suggests there are two methyl groups at position 1 of the molecule. Choice B is incorrect because it suggests there are five carbons in the longest carbon chain, whereas there are only four.
