Question

General formula of alkenes and alkyl radicals are respectively:

• A. $C_n{H}_{2n}$ and $C_n{H}_{2n+1}$
• B. $C_n{H}_{2n}$ and $C_n{H}_{2n+2}$
• C. $C_n{H}_{2n-1}$ and $C_n{H}_{2n}$
• D. $C_n{H}_{2n+1}$ and $C_n{H}_{2n+2}$

Answer 1

The correct option is A $C_n{H}_{2n}$ and $C_n{H}_{2n+1}$

General fromula for Alkane, Alkene and Alkyne are $C_n{H}_{2n+2}$, $C_n{H}_{2n}$, and $C_n{H}_{2n-2}$.
General formula for alkyl radical is $C_n{H}_{2n+1}$
Hence opiton A is correct
