Tardigrade Admin · Accepted Answer

Addition on a triple bond occurs by syn-addition of hydrogen. The configuration of double bond already present is cis. The compound formed will have a plane of symmetry and thus it will be optically inactive. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/2e6439868eab676017deec5ab2ec54e6-.png" />
