A)3-methyl-1-methylbutane 
B)1-methoxy-3-methylpentane

D)1-methoxy-3-methylbutane

Quizplus · Accepted Answer

The compound has a chain of 5 carbons, with a methyl group attached at the third carbon and a methoxy group (OCH3) attached at the first carbon. Therefore, the IUPAC name is 1-methoxy-3-methylbutane. Choice A is incorrect because there cannot be two methyl groups attached to the same carbon. Choice B is incorrect because the chain has 5 carbons, not 6. Choice C is incorrect because the ether group (O-R) should be attached to the first carbon of the chain, not the third.
