alleryThe general formula for alkanes is:
ACnH2n plus 4
BCnH2n plus 6
CCnH2n plus 8
DCnH2n plus 2
Answer & Solution
Correct answer: D. CnH2n plus 2
1. Each additional carbon brings two more hydrogens.
2. The chain ends contribute two extra.
3. The general formula for alkanes is CnH2n plus 2.
4. So the answer is CnH2n plus 2.
