Which of the following is a secondary alcohol? (2021) 2021

Step 1: Understand what a secondary alcohol is. A secondary alcohol is an alcohol where the hydroxyl group (-OH) is attached to a carbon atom that is connected to two other carbon atoms.
Step 2: Identify the structure of 2-Pentanol. It has the formula C5H12O and its structure shows that the -OH group is attached to the second carbon in the chain.
Step 3: Check the carbon to which the -OH group is attached. In 2-Pentanol, the second carbon is connected to two other carbon atoms, confirming it is a secondary carbon.
Step 4: Conclude that since the -OH group is on a secondary carbon, 2-Pentanol is indeed a secondary alcohol.
