Answer 1

2-ethoxibutan-2-ol

Step-by-step explanation:

Hello,

In this case, under acidic conditions, the reaction attached on the picture is carried out in order to form the hemiacetal 2-ethoxibutan-2-ol as long as there is 1 equivalent of ethanol. If 2 equivalents react, the product will be an acetal.

Best regards.

Answer 2

Here is the answer of your question. Hemiketal is formed in when alcohol is added in one equivalent. If ethanol is added in excess or in 2 equivalent then ketones will give ketals.
