Cycloalkanes have the general formula A) C_nH_2n-4. B) C_nH_2n-2. C) C_nH_2n. D) C_nH_2n+2. E) C_nH_2n+4.

Question

Quizplus · Accepted Answer

The general formula for cycloalkanes is CnH2n, where n is the number of carbons in the ring. Since the number of hydrogens in cycloalkanes is twice the number of carbons, the formula becomes CnH2n. In this case, the cycloalkane has only carbon and hydrogen atoms, so the formula becomes CnH2n. However, since the carbon atoms in the ring are bonded to two other carbon atoms, the formula is modified to CnH2n, where n is the number of carbon atoms in the ring. Therefore, the correct answer is C, which is the general formula for cycloalkanes.
