Download Solution PDFThe correct answer is option 3, i.e. C3H8.
- The molecular formula of propane is C3H8.
- Alkanes are acyclic hydrocarbons in which carbon-carbon atoms have a single bond between them, i.e. they are saturated hydrocarbons.
- The general formula for alkanes is CnH2n+2, where 'n' is the number of carbon atoms.
- Propane is the third member of the alkane family with 3 carbon atom. If we put the number of carbon and hydrogen atoms present in propane in the above-mentioned formula, we will find that it holds true.
- CH4 is Methane, the first member of the alkane family.
- C4H10 is Butane, the fourth in the line of alkanes.
- C2H6 is Ethane, the second member of the alkane family.
- The lower alkanes from C1 to C4 are gases, from C5 to C16 are liquids and beyond that are solids.
