    Topic:- Identification Question.

    [ANSWERS]

    Ans 1.

    Ans 2.

    Ans 3. The compound X is CH3Br and Y is CH3MgBr The compounds of the type Y are called

    Grignard reagent.

    Ans 4. The compound B is obtained by oxidation of C4H10O and gives positive iodoform test

    and also reacts with CH3MgBr , it must be methyl Ketone , it must be methyl ketone

    having four carbon atoms i.e, CH3COCH2CH3 .

    This can be obtained by oxidation of 2 butanol i.e , CH3 CH CH2 CH3 Therefore , the

    reactions are. OH

    Ans 5.

    The aromatic compound having molecular formula C6H6O and which gives a mixture of

    Ans 6.

    Since acetic acid & propionic acid are the products of oxidation of C which is a ketone, C is

    CH3 CH2 CH2CO CH3. Since it is the oxidation product of B, therefore

    The reactions are

    Ans 7.

    Ans 8.
