Alkanes are known as saturated hydrocarbons because they contain only carbon-hydrogen single bonds.

• True

• False

Alkenes are:

• saturated, because they do not have the maximum number of hydrogen atoms
• unsaturated, because they do not have the maximum number of hydrogen atoms
• unsaturated, because they have the maximum number of hydrogen atoms
• aromatic compounds

The general formulas for alkanes, alkenes and alkynes are:

• alkane: C_nH_2n+2

  alkene: C_nH_2n

  alkyne: C_nH_2n-2

• alkane: C_nH_2n

  alkene: C_nH_2n+2

  alkyne: C_nH_n+4

• alkane: C_nH_2n-2

  alkene: C_nH_2n

  alkyne: C_nH_2n+2
