Answer:
The correct answer is 2
CH_3-(CH_2)_9-CN and CH_3(CH_2)_9-COOC_2H_5
Explanation:
DIBAL-H is known as DiIsoButylAluminium Hydride - reducing agent.
Aldehydes are formed due to the reduction of carboxylic acids.
It causes the partial reduction of the cyanide group along with the ester group.
The aldehydes are formed as the product due to the hydrolysis reaction.
These reduction process is stereospecific and chemoselective.
To prevent the further reduction process low temperature is maintained.
