Alcohol Reactions

Question 1

Alcohol —> Carboxylic Acid. Name the reagents. Name the process.

Answer 1

H+/MnO4 - OR H+/Cr2)7 2-. This is an oxidation reaction as a double C=O bond is being added.

Question 2

Alcohol —> Haloalkane. Name the reagents and type of reaction.

Answer 2

PCl3 / PCl5 / SOCl2. This is a substitution reaction.

Question 3

Alcohol —> Alkene. Name the reagents and its properties. Name the process.

Answer 3

Heat / Concentration H2SO4. Sulfuric acid is a dehydrating agent which removes the OH group. This is an elimination reaction.

Question 4

Haloalkane —> Alcohol. Name the reagent and type of reaction.

Answer 4

KOH (aq). This is a substitution reaction where the OH group in KOH replaces the halogen group in the haloalkane.

Question 5

Alkene —> Alcohol. Name the reagents and process.

Answer 5
