Question

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

Answer 2

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.
