Question

Choose the correct answer among the alternatives given :
Classify the following compounds as primary, secondary and tertiary halides.
(i) 1-Bromobut-2-ene
(ii) 4-Bromopent.2-ene
(iii) 2-Bromo-2-methylpropane

• A. (i)-secondary, (ii)-tertiary, (iii)-primary
• B. (i)-secondary, (ii)-primary, (iii)-tertiary
• C. (i)-primary, (ii)-tertiary, (iii)-secondary
• D. (i)-primary, (ii)-secondary, (iii)-tertiary

Answer 1

Answer: (D)

(i)-primary, (ii)-secondary, (iii)-tertiary

Primary halides are the compounds on which the halide ion is attached to the primary carbon. This can be seen in 1-Bromo but-2-ene. Secondary halides are the compounds in which the halide ion is attached to the secondary carbon that is in 4-Bromopent.2-ene. Tertiary halides are the compounds in which the halide ion is attached to a tertiary carbon. This can be seen in 2-Bromo-2-methylpropane.

Therefore D is the correct option.
