NEET Chemistry Organic Preparations Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Sodium Carbonate Extract | (i) Blue color with Starch |
| (b) Iodine Production Reaction | (ii) Curdy white precipitate |
| (c) Nitrite Ion Test | (iii) Violet color in organic layer |
| (d) Chlorine Gas Detection | (iv) Yellow color in NaOH solution |
a-ii, b-iii, c-i, d-iv
a-iv, b-ii, c-iii, d-i
a-ii, b-iv, c-i, d-iii
a-iii, b-ii, c-iv, d-i
Correct Answer
Detailed Explanation
Sodium carbonate extract, when acidified with dilute HNO3 and treated with silver nitrate, gives a curdy white precipitate (a-ii). The iodine production reaction leads to a violet color in the organic layer when chlorine water is added (b-iii). The nitrite ion test involves producing a blue color with starch when treated with acid (c-i). Finally, the chlorine gas detection can turn a solution yellow when the gas is passed through NaOH (d-iv).
