    Directions : (16 - 20)
    Case IV : Read the passage given below and answer the following questions from 16 to 20.
    A compound (X) containing C, H and O is unreactive towards sodium. It also does not react with Schiff's reagent. On refluxing with an excess of hydroiodicacid, (X) yields only one organic product (Y). On hydrolysis, (Y) yields a new compound (Z) which can be converted into (Y) by reaction with red phosphorus and iodine. The compound (Z) on oxidation with potassium permanganate gives a carboxylic acid. The equivalent weight of this acid is 60.
    The compound (X) is an

    A) acid

    B) aldehyde

    C) alcohol

    D) ether.

    Correct Answer: D

    Solution :

    Since the compound X is unreactive towards sodium so, it is neither an acid nor an alcohol. Since the compound X is unreactive towards Schiff's base so it is not an aldehyde. The compound X forms only one product on reaction with excess HI, indicates that the compound X may be ether.
