Question

Which one of the following is an allylic halide ? (A) 2-Chlorobutane (B) Chloroethene (C) 3-bromopropene (D) 2-Chlorotoluene

Tardigrade Admin · Accepted Answer

When halogen atom attached with adjacent position of unsaturation, the position is called allylic position and compound is called allylic halide. In 3-bromopropene, halogen atom (bromine) attached with adjacent position of double bond, so compound is called allylic bromide. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/7de5ab5d4b6c1741b70aca492d7a35f1-.png" />
