Question

Choose the correct comparison of heat of hydrogenation for the following alkenes. (A) II > IV < III < V < I (B) III < IV < I < V < II (C) V < IV < III < I < II (D) IV < V < I < III < II

Tardigrade Admin · Accepted Answer

Greater the stability of alkene, lower the heat of hydrogenation. Correct stability order is: <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/1338d76238dfa5b7ae5ad25b446a86ed-.png" />

Q. Choose the correct comparison of heat of hydrogenation for the following alkenes.

$II > I V < III < V < I$

$III < I V < I < V < II$

$V < I V < III < I < II$

$I V < V < I < III < II$

Greater the stability of alkene, lower the heat of hydrogenation. Correct stability order is:
