Which of these alkyl halides cannot be used to prepare amines using gabriel synthesis?

a. 1-bromopentane

b. 1-bromo-3-methylbutane

c. 2-bromo-3-methylpentane

d. 1-bromo-2,3-dimethylbutane

e. 2-bromo-2,3-dimethylbutane?

For Gabriel synthesis halides should be primary.

a. 1-bromopentane - primary

b. 1-bromo-3-methylbutane - pimary

c. 2-bromo-3-methylpentane - secondary - cannot be used

d. 1-bromo-2,3-dimethylbutane - primary

e. 2-bromo-2,3-dimethylbutane - tertiary - cannot be used

I think it should be like this
