Question

What functional group consists of a carbon atom double-bonded to an oxygen atom?

Carbohydrate group
Carbonyl group
Hydroxyl group
Ketone group

Answer 1

Carbonyl group

Step-by-step explanation:

A carbonyl group is a functional group composed of a carbon atom double-bonded to an oxygen atom (presented as C ═ O). Ketones and aldehydes are examples of simple compounds that contain a carbonyl group.

Answer 2

The answer to your question is: letter B.

Step-by-step explanation:

Carbon atom double-bonded to an oxygen atom C= O,

a) Carbohydrate group this group does not exist

b)Carbonyl group This option is right, carbonyl group is C=O

c) Hydroxyl group This option is incorrect, hydroxyl group is OH, very different from C=O

d) Ketone group Ketone group does not exist, ketones have the same functional group as aldehydes (C=O)
