D Cyclic hydrocarbons that contain one double bond SECOND QUESTION. With a general formula of C n H 2n n is an integer greater than 2 they have two fewer hydrogen atoms than an alkane with the same number of carbon atoms. What is the general molecular formula for cycloalkanes.
Cyclic compounds are not all flat molecules.
Note that the general formula for a cycloalkane composed of n carbons is C n H 2n and not C n H 2n2 as for alkanes. Carbon surrounded by four atoms. Hydrocarbons of this kind are classified as alkanes or cycloalkanes depending on whether the carbon atoms of the molecule are arranged only in chains or also in rings. The general formula for a cycloalkane is C n H 2 n.
