Answer 2

Answer:

Molecules of 1-propanol and 2-propanol have different structural formulas.

Therefore, option (4) is correct.

Explanation:

The difference between molecules of 1-propanol and 2-propanol is the position of -OH (alcoholic) group.

• The main difference between 1-propanol and 2-propanol is that in 1 propanol has its hydroxyl group (-OH) attached to the end carbon C-1 of the carbon chain whereas in 2-propanol has the hydroxyl group (-OH) attached to the middle carbon atom or C-2 of the carbon chain.
• 1-propanol as well as 2-propanol are two isomeric structures of propanol molecule.
• Both 1-propanol as well as 2-propanol has molecular formula C₃H₈O and molecular mass 60g.
• 1-propanol is a primary alcohol while 2-propanol is a secondary alcohol.
