Use the following information to answer the next question.
CH3 - C(=O) - O - CH3
The functional group present in compound (i) is a(n)
Question 26 options:
a) carboxyl group
b) ester group
c) hydroxyl group
d) alkenyl group
e) amide group
b) ester group
The functional group present in compound (i), CH3 - C(=O) - O - CH3, is an ester group. Therefore, the correct option is b) ester group.
To determine the functional group present in compound (i), we need to identify the different groups attached to the carbon atom that is double-bonded to the oxygen atom.
The compound you have provided is CH3 - C(=O) - O - CH3.
The group attached to the carbon atom is C(=O), which is a carbonyl group.
Next, we look at the groups attached to the oxygen atom. There is a methyl group (CH3) attached to one side of the oxygen atom, and another methyl group (CH3) attached to the other side of the oxygen atom.
Based on the arrangement of the carbonyl group and the two alkyl groups attached to the oxygen atom, we can conclude that compound (i) has an ester group.
Therefore, the correct answer is b) ester group.
