Explanation:
Q7. In alkanes, the bonds present are single covalent bonds. In alkenes, there are double covalent bonds. In alkynes, there are triple covalent bonds.
Q8. In terms of phase, the alkanes are all gases or liquids at room temperature, while the alkenes and alkynes are all gases at room temperature. In terms of the number of carbon atoms, the alkanes generally have more carbon atoms than the alkenes, which generally have more carbon atoms than the alkynes. In terms of structure, the alkanes are all straight-chain or branched hydrocarbons, the alkenes are all unsaturated hydrocarbons with at least one double bond, and the alkynes are all unsaturated hydrocarbons with at least one triple bond. In terms of boiling point, the alkanes generally have higher boiling points than the alkenes, which generally have higher boiling points than the alkynes. This is due to the increasing number of carbon atoms and the increasing number and strength of the bonds present in each group of hydrocarbons.
Q9. The next alkane will have a higher boiling point than the current alkane because it will have more carbon atoms and stronger single covalent bonds. The next alkene will have a higher boiling point than the current alkene because it will have more carbon atoms and stronger double covalent bonds. The next alkyne will have a higher boiling point than the current alkyne because it will have more carbon atoms and stronger triple covalent bonds.
Q10. Some hydrocarbons are gases because they have relatively low boiling points, which allows them to easily evaporate and become gases at room temperature. Others are liquids because they have relatively high boiling points, which prevents them from easily evaporating and becoming gases at room temperature.
Q11. There are many hydrocarbon compounds because hydrocarbons can form a wide variety of compounds by reacting with each other and with other elements. This is due to the versatility of carbon and its ability to form strong bonds with a wide variety of elements.
Q12. Hydrocarbon compounds that are gases include alkanes, alkenes, and alkynes. Hydrocarbon compounds that are liquids include alkanes. Gaseous hydrocarbon compounds are used as fuels, while liquid hydrocarbon compounds are used as solvents, lubricants, and raw materials for the chemical industry.
