What are hydro carbons ? Give the difg saturated & unsaturated |
| Answer» All the carbon compounds which contain just carbon and hydrogen are called hydrocarbons.\tSaturated hydrocarbonsUnsaturated hydrocarbons(i) Saturated hydrocarbons are the compounds containing only single covalent bonds. These are also known as alkanes.\xa0(i) Unsaturated hydrocarbons are the straight chain compounds containing double or triple covalent bonds. Hydrocarbons with a double bond between carbon atoms are known as alkenes.\xa0Hydrocarbons with triple bonds between carbon atoms are known as alkynes.\xa0(ii) These compounds have more number of hydrogen atoms when compared to its corresponding unsaturated hydrocarbons.(ii) These compounds have less number of hydrogen atoms when compared to its corresponding unsaturated hydrocarbons.(ii) These compounds are less reactive.(iii) These compounds are more reactive.(iv) These compounds under go substitution reactions. CH4\xa0+ Cl2 → CH3Cl + HCl(iv) These compounds under go addition reactions. Ex: CH2=CH2\xa0+ H2\xa0→ CH3\xa0- CH3\t | |
