Question

Which among the following compound on treatment with DIBAL-H yields dodecanal at 195 K?

Options

• \[\ce{CH3CH = CH CH2 CN}\]

• \[\ce{C2H5CN}\]

• \[\ce{CH3(CH2)10COOCH3}\]

• \[\ce{C6H5CN}\]

Answer 1

\[\ce{CH3(CH2)10COOCH3}\]

Explanation:

Dodecanal = \[\ce{CH3(CH2)10CHO}\]

\[\ce{CH3(CH2)10COOCH3 ->[DIBAL-H] \underset{\text{Do decanal}}{CH3(CH2)10CHO}}\]

DIBAL - H converts esters into aldehyde.
