Question

The molecule which is free from angular strain is: (A) Cyclopropane (B) Cyclobutane (C) Cyclopentane (D) Cyclohexane

Tardigrade Admin · Accepted Answer

Cyclohexane adopts a conformation is which all the bond angles between carbon atoms are close to tetrahedral angle, i.e, 109.5 , called chair conformation. This conformation is free from angular strain as well as torsional strain. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/3598596f76c451a0e12ca42836ae9f20-.png" />
