The correct answer is option 2 i.e C4H10.
Concept:
Hydrocarbons
- Compounds made of carbon and hydrogen atoms only are called hydrocarbons.
- Saturated hydrocarbons:
- The hydrocarbons in which carbon atoms are singly bonded are called saturated hydrocarbons.
- Saturated hydrocarbons are also called alkanes or paraffin.
- The general formula of alkane– CnH2n+2.
- Unsaturated hydrocarbons:
- The hydrocarbons in which carbon atoms are either doubly or triply bonded are called unsaturated hydrocarbons.
- Doubly bonded (carbon atoms) hydrocarbons are called alkenes.
- The general formula of alkene is CnH2n.
- The formula for alkane should be mentioned CnH2n+2
