Question

In which of the following cases will the compound be a tertiary (3°) halogen compound? (X=halogen atom)

(a) R’=R”=H

(b) R’=CH3, R”=H

(c) R’=H, R”=CH3

(d) R’=R”=CH3

The question was asked in examination.

The query is from Haloalkanes Classification in portion Haloalkanes and Haloarenes of Chemistry – Class 12

Answer 1

Right option is (d) R’=R”=CH3

The best I can explain: When R and R’ both are CH3 groups, then the carbon atom bonded to the halogen will have three alkyl groups attached to it including the benzene ring.
