Matching Trade Names to Chemical Names
This question requires matching chemical compounds, identified by their common trade names in List-I, with their correct chemical names provided in List-II. Understanding these common names and their corresponding chemical formulas is crucial in chemistry.
Understanding the Lists Provided
List-I contains common trade names for various chemical substances, while List-II provides their corresponding chemical names and formulas.
| List-I (Trade Name) |
| A. Bleaching powder |
| B. Baking soda |
| C. Washing soda |
| D. Plaster of Paris |
| List-II (Chemical Name) |
| 1. Sodium bicarbonate |
| 2. Sodium carbonate, 10 water |
| 3. Calcium oxychloride |
| 4. Calcium sulphate, 1/2 water |
Detailed Matching of Trade Names and Chemical Names
Let's examine each trade name from List-I and find its corresponding chemical name from List-II:
A. Matching Bleaching Powder
The trade name Bleaching powder refers to Calcium oxychloride. Its chemical formula is typically represented as \(\text{Ca}(\text{OCl})_2\). This corresponds to item 3 in List-II.
B. Matching Baking Soda
The common name Baking soda is the widely used name for Sodium bicarbonate. Its chemical formula is \(\text{NaHCO}_3\). This matches item 1 in List-II.
C. Matching Washing Soda
Washing soda is the trade name for Sodium carbonate decahydrate. The name "Sodium carbonate, 10 water" accurately describes this hydrated salt, with the formula \(\text{Na}_2\text{CO}_3 \cdot 10\text{H}_2\text{O}\). This corresponds to item 2 in List-II.
D. Matching Plaster of Paris
Plaster of Paris is the common name for Calcium sulphate hemihydrate. The description "Calcium sulphate, 1/2 water" refers to its chemical composition, represented by the formula \(\text{CaSO}_4 \cdot \frac{1}{2}\text{H}_2\text{O}\). This matches item 4 in List-II.
Determining the Correct Code
Based on the detailed matching:
- A (Bleaching powder) matches with 3 (Calcium oxychloride).
- B (Baking soda) matches with 1 (Sodium bicarbonate).
- C (Washing soda) matches with 2 (Sodium carbonate, 10 water).
- D (Plaster of Paris) matches with 4 (Calcium sulphate, 1/2 water).
Therefore, the correct sequence for A B C D is 3 1 2 4.
