Questions asked by users might not always be phrased in the clearest way.

2-propanol reacts with iodine in aqueous solution of NaOH to produce light yellow precipitate but compound Qdoes not. Explain the observation

Accepted Answer

2-propanol is a secondary alcohol and undergoes oxidation in the presence of strong oxidizing agents such as iodine in an alkaline medium to form a yellow precipitate of iodoform. Compound Q, if it is a primary alcohol or does not have a methyl group attached to the carbon bearing the -OH group, will not undergo this reaction and no precipitate will be formed.
