Q17-39E - Organic Chemistry (Mcmurry)

Question

Which of the eight alcohols that you identified in Problem 17-38 react with ${\mathbf{CrO}}_{\mathbf{3}}$ in aqueous acid? Show the products you would expect from each reaction

Step-by-Step Solution

Answer

The reaction followed as:

Step1: Reaction with chromic acid

Chromic acid is the reagent used for the reduction of the alcohol to carboxylic acid, aldehyde and ketone.

Step2: Isomer of C 5 H 12 O    

Isomers of ${\mathrm{C}}_5{\mathrm{H}}_{12}\mathrm{O}$ given below as u see are the compound have same molecular formula the only difference is in their structure that is by changing the position of hydroxy group and by branching the carbon chain as shown:

Step3: Reaction of the isomer with chromic acid

Chromic acid convert primary alcohol into carboxylic acid and secondary alcohol into ketone and tertiary do not now show reaction like isomer 2methyl2 butanol as shown:
