Question

All members of the alkene series of hydrocarbons have the general formula:

Select one:
a. CnH2n-2
b. CnH2n+2
C. CnHn
d. CnH2n

Answer 1

D: CnH2n

Step-by-step explanation:

Unsaturated hydrocarbons have double and/or triple bonds between carbon atoms. Those with double bond assuming they have non-cyclic structures are called alkenes with the general formula C_nH_2n. Meanwhile the hydrocarbons that possess triple bonds are called alkynes and possess the general formula CnH2n-2.

Looking at the options, for alkenes, the correct answer is option D
