question 30 of 30
what class of organic molecule is shown below?

o
||
h₃c-c-h

a. aldehyde
b. carboxylic acid
c. ketone
d. alcohol

Explanation:

To determine the class of the organic molecule, we analyze its functional group. The given structure has a carbonyl group ($C=O$) with one hydrogen atom attached to the carbonyl carbon and one alkyl group ($-CH_3$). Aldehydes have the functional group $-CHO$ (carbonyl carbon bonded to a hydrogen and an alkyl/group), which matches this structure. Carboxylic acids have $-COOH$, ketones have carbonyl carbon bonded to two alkyl groups, and alcohols have $-OH$. So the molecule is an aldehyde.

Answer:

A. Aldehyde
