Which of the following is the general formula for saturated hydrocarbons? A. CnH2n + 2 B. CnH2n – 2 C. CnH2n + 1 D. CnH2n – 1

CnH2n + 2
CnH2n - 2
CnH2n + 1
CnH2n - 1

The correct answer is A. CnH2n + 2.

A saturated hydrocarbon is an alkane, which is a hydrocarbon that contains only single bonds between carbon atoms. The general formula for an alkane is CnH2n + 2, where n is the number of carbon atoms in the molecule.

Option B, CnH2n – 2, is the general formula for an alkene, which is a hydrocarbon that contains one or more double bonds between carbon atoms.

Option C, CnH2n + 1, is the general formula for an alkyne, which is a hydrocarbon that contains one or more triple bonds between carbon atoms.

Option D, CnH2n – 1, is not the general formula for any type of hydrocarbon.
