What is the general molecular formula for alkenes?
Options
- AC _n H _ 2n+2
- BC _n H _ 2n
- CC _n H _ 2n-2
- DC _n H _n
Correct answer
B. C _n H _ 2n
Step-by-step solution
Alkenes are unsaturated hydrocarbons that contain at least one carbon-carbon double bond. For an aliphatic, non-cyclic alkene with one double bond, the general molecular formula is C _n H _ 2n , where n is the number of carbon atoms. C _n H _ 2n+2 is the general formula for alkanes. C _n H _ 2n-2 is the general formula for alkynes. Answer: C _n H _ 2n
