2. The formula of propane is C₄H₁₀.

1. Statement 1 is correct
2. Statement 2 is correct
3. Both are correct
4. Both are incorrect

Answer 1

Correct Answer - Option 1 : Statement 1 is correct

The correct answer is 1 i.e. Statement 1 is correct.

Explanation:

• This compound contains 3 carbon atom which is indicated by writing 'prop'.
• This compound has all single bonds, so it is saturated.
• The saturated hydrocarbon is indicated by the ending 'ane'.
• On joining 'prop' and 'ane', the IUPAC name of its compound becomes 'propane'.
• This common name of C₃H₈ hydrocarbon is also propane. 
• Thus, the IUPAC name as well as the common name of the hydrocarbon C₃H₈ is the same, propane. 
• We conclude that for the saturated hydrocarbons containing up to 3 carbon atoms, the IUPAC and common names are just the same. 
• But this is not so for the saturated hydrocarbons containing 4 or more carbon atoms.
