Question

question 3 (1 point)
the general formula for a cycloalkane can be represented by which of the following?

c_nh_n
c_nh_{2n + 2}
c_nh_{2n}
c_nh_{2n - 2}

Explanation:

Cycloalkanes are cyclic hydrocarbons. The general formula for alkanes (non - cyclic) is \(C_{n}H_{2n + 2}\). When forming a cycloalkane (a ring structure), one degree of unsaturation is introduced. Each degree of unsaturation removes 2 hydrogen atoms. So, for cycloalkanes, the general formula is \(C_{n}H_{2n}\).

Answer:

\(C_{n}H_{2n}\) (the third option).
