alleryThe general formula of an alkane is:
ACnH2n
BCnHn
CCnH2n-2
DCnH2n+2
Answer & Solution
Correct answer: D. CnH2n+2
1. Alkanes are saturated hydrocarbons with only single bonds.
2. The general formula is CnH(2n+2).
3. Methane (CH4) gives n=1, so 2n+2=4 hydrogens, matching the formula.
4. So the answer is CnH(2n+2).
