A) 2,2-dimethyl-4-butanol 
B) 3,3-dimethyl-1-butanol 
C) 1-tert-butyl-2-ethanol 
D) 2-sec-butyl-1-ethanol

Accepted Answer

The compound has a primary alcohol functional group and a four-carbon chain. The longest continuous carbon chain contains four carbons, so the base name is butanol. The alcohol group is on the first carbon, so it is 1-butanol. There are two methyl groups on the third carbon, so it is 3,3-dimethyl-1-butanol.
