It is based on general formula CnH2n n hence it could be an alkene or a cycloalkane. Since, it has no double bond, it must be a cycloalkane. It has one —CH3, group as <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/99ff8a07be4adb981da6e8e2f582350e-.png" />
