d. 2º alcohol.
Work Step by Step
a. The OH- in this alcohol is bonded to a Carbon atom that is bonded to 1 other Carbon. Therefore, it is a 1º alcohol.
b. The F- in this alkyl halide is bonded to a Carbon atom that is bonded to 2 other Carbons. Therefore, it is a 2º alkyl halide.
c. The Br- in this alkyl halide is bonded to a Carbon atom that is bonded to 2 other Carbons. Therefore, it is a 2º alkyl halide.
d. The OH- in this alcohol is bonded to a Carbon atom that is bonded to 2 other Carbons. Therefore, it is a 2º alcohol.
