The general formula of Saturated hydrocarbons is CnH2n.
Only single bonds are present in saturated hydrocarbons. I.e. Saturated hydrocarbons are alkanes. The general formula of alkanes is CnH2n+2.
(a) What are hydrocarbons? Explain with examples. (b) Explain the meaning of saturated and unsaturated hydrocarbons with two examples each. (c) Give the names and structural formulae of one saturated cyclic hydrocarbon and one unsaturated cyclic hydrocarbon. (d) Give one example of a hydrocarbon, other than pentane, having more than three isomers. (e) How many isomers of the following hydrocarbons are possible? (i) C3H8 (ii) C4H10 (iii) C5H12 (iv) C6H14
