Question

Match the following compunds with their categories.

• A. Alkane
• B. Alkene
• C. Alkyne
• D. Aromatic hydrocarbon

Answer 1

1. Alkanes - saturated open chain hydrocarbons
- contain carbon-carbon single bonds
- General formula: $C_n{H_{2n}}_{+2}$

2. Alkenes - unsaturated hydrocarbons
- contain at least one carbon–carbon double bond
- General formula:$C_n{H}_{2n}$

3. Alkynes - unsaturated hydrocarbons
- contain at least one carbon-carbon triple bond
- General formula: $C_n{H}_{2n-2}$

4. Aromatic hydrocarbons- Cyclic hydrocarbons with delocalized electrons between carbon atoms of the ring.
E.g- Benzene.
