[2 Marks]

Q.

The suffix used for saturated hydrocarbons is:

1. -ane

2. -ene

3. -yne

4. -ol

Q. The general formula for alkynes is:

1. ${\text{C}}_{\text{n}}{\text{H}}_{2\text{n}+2}$
2. ${\text{C}}_{\text{n}}{\text{H}}_{\text{n}}$
3. ${\text{C}}_{\text{n}}{\text{H}}_{2\text{n}}$
4. ${\text{C}}_{\text{n}}{\text{H}}_{2\text{n}-2}$

Q. __________ is the most stable compound amongst the following.

1. But-2-ene
2. But-1-yne
3. But-1-ene
4. Butane

Q. Identify the unsaturated hydrocarbons.

1. Propyne
2. Butene
3. Ethene
4. Pentene
5. Hexyne
6. Methane
7. Heptane
8. Octane

Q. Ethene $(H_{2}C=C{H}_2)$ is an unsaturated hydrocarbon.

1. True
2. False

Q. The hydrocarbons having double or triple bond in their structure are unsaturated hydrocarbons.

1. True
