Question

what is/are the carbonyl product(s) formed when the alcohol below is oxidized with k₂cr₂o₇?
ch₃(ch₂)₄cooh
no reaction occurs.

Explanation:

Step1: Identify alcohol type

The given alcohol is a secondary alcohol.

Step2: Recall oxidation of secondary alcohol

Secondary alcohols are oxidized to ketones by $K_2Cr_2O_7$.

Step3: Analyze options

The first option is a carboxylic - acid, second is an alkene, third is a ketone, fourth has a ketone and a carboxylic - acid, and fifth is no reaction. The correct product for oxidation of a secondary alcohol with $K_2Cr_2O_7$ is a ketone.

Answer:

The third option (the ketone structure)
