Question

Which of the following is the IUPAC name of tert-butyl alcohol?
A) 1-butanol
B) 2-butanol
C) 2-methyl-1-propanol
D) 2-methyl-2-propanol

Accepted Answer

Tert-butyl alcohol has a branched chain structure with a tertiary carbon atom, therefore the correct IUPAC name is 2-methyl-2-propanol. A) 1-butanol is a straight chain primary alcohol. B) 2-butanol is a straight chain secondary alcohol. C) 2-methyl-1-propanol is a branched chain primary alcohol, but it has a primary carbon atom, not tertiary as in tert-butyl alcohol.
