Question

Below is a general reaction scheme for the conversion of a methyl ketone (R is undefined but does not change in the reaction) to a carboxylic acid using the haloform reaction, where X = Br, Cl, or I. This problem is simply a general chemistry redox reaction question applied to organic molecules.

a) Balance the reaction scheme by adding stoichiometric coefficients as appropriate.

b) Circle and label ALL atoms in the starting materials that are oxidized (Hint: assign oxidation numbers, starting with atoms that are familiar to you from general chemistry).

c) Circle and label ALL atoms in the starting materials that are reduced

d) What is/are the oxidizing agent(s) in this reaction?

e) Circle and label the haloform.

Explanation / Answer

For the given type of reaction

a) Balanced equation,

RCOCH3 + 3X-X + 4NaOH ---> RCOONa + CHX3 + 3NaX + 3H2O

b) Species oxidized are,

RCOCH3

c) Species reduced are,

X-X

d) Oxidizing agent is,

X-X

e) Haloform in the reaction,

CHX3
