Question

what are hydrocarbons ? Give the structural differences between saturated and unsaturated hydrocarbons. Give two examples of each.

Answer 1

Compounds of hydrogen & carbon are known as hydrocarbons.
Ex- Methane & Ethane etc.
Saturated hydrocarbons have single bond b/w the atoms whereas unsaturated hydrocarbons have 2 (alkenes) or 3 (alkenes) bonds b/w the atoms.
Ex- Methane CH4

Answer 2

“Hydrocarbons” are the organic compounds which contain carbon along with hydrogen atoms bonded to each other.  

Differences between unsaturated and saturated hydrocarbons:

SATURATED HYDROCARBONS:

• Saturated hydrocarbons are the compounds that have a single covalent body and are called alkanes.

• Saturated hydrocarbons have more hydrogen atoms as compared to unsaturated hydrocarbons.  
• Examples for saturated hydrocarbons are ethane, methane

UNSATURATED HYDROCARBONS:

• Unsaturated hydrocarbons are compounds that have “double or triple covalent” bonds.
• Unsaturated hydrocarbons with double covalent bonds are called "alkenes" and the ones with triple covalent bonds are called alkynes.  

• Examples for unsaturated hydrocarbons are propene, butyne.
