In the following reaction {\CH}_3- {\CH}= {\CH}- {\CH}_2- {\OH} \stackrel{\text{ PCC }{\to}} the product formed is:

Correct Answer is : CH3−CH=CH−CHO

{\CH}_3- {\CHO} and {\CH}_3 {\CH}_2 {\OH}

{\CH}_3- {\CH}_2- {\CH}_2- {\CHO}

CBSE Class 12 Chemistry 2022 Term 1 Paper - Question 28

Question : 28 of 55

Marks: +1, -0

In the following reaction

{\CH}_3- {\CH}= {\CH}- {\CH}_2- {\OH} {→}↖{\;\text " PCC "\;}

the product formed is:

Solution:

{\CH}_3- {\CH}= {\CH}- {\CH}_2- {\OH} {→}↖{\;\text " PCC "\;}

{\CH}_3- {\CH}= {\CH}- {\C↙{∥ }↙{\O}-\H }

Where PCC: Pyridinium chloro oxochromate.
PCC oxidises primary alcohols to aldehydes
