How will you distinguish the primary, secondary and tertiary alcohols by Victor Meyer’s method ? |
|
Answer» Solution :Victor Meyer's test: (i) Alcohol is converted into alkyl iodide by treatment with `P//I_(2)`. (ii) The alkyl iodide is then converted into nitro alkane by sivler nitrite `(AgNO_(2))`. (III) The nitro alkane is treated with nitrous acid `(HNO_(2))` and then with aqueous KOH. (iv)The `1^(@), 2^(@)` and `3^(@)` alcohols are identified from the colour of the PRODUCT. (a) Primary alcohol: `underset("Ethanol"1^(@))(CH_(3)-CH_(2)-OH) overset(P//I_(2)) to underset("Ethyl iodide") (CH_(3)CH_(2)I) overset(AgNO_(2)) to underset("Nitro ethane") (CH_(3)CH_(2)NO_(2)) overset(O=N -OH) to underset("Nitroxime")underset(NO_(2))underset(|)(CH_(3)C = NOH) overset(KOH) to underset("Potassium salt of nitrolic acid (Red)")underset(NO_(2))underset(|)(CH_(3)C=N-OK^(+))` (b) Secondary alcohol:  ( c)
