Answer 2

Option (b) Propanol.

Explanation:

Propanol belongs to the functional group "Alcohol" with the molecular formula C3H7OH.

Here, for Propanol, Alcohol's suffix (ol) have been added for Propan(ol). While pronouncing Propanol, you can clearly know that Propanol is belongs to the functional group "Alcohol" by seeing "ol" in the members like Propan(ol), Butan(ol), etc..,

I think Option (d) also belongs to functional group of "Alcohol". Because while typing the option, you have missed the letter "L" in Ethanol. So, I think Option d also belongs to the functional group of Alcohol.
