Vedclass · Answer

(C) cycloalkane is a saturated hydrocarbon that contains one ring structure. For an open-chain alkane,the general formula is $C_n H_{2n+2}$. When a ring is formed,two hydrogen atoms are removed from the chain to connect the ends,resulting in the loss of $2$ hydrogen atoms. Therefore,the general formula for a cycloalkane becomes $C_n H_{2n+2-2} = C_n H_{2n}$.
