Write the structural formula of the following :
(i) Di-isopropyl ether (ii) Divinyl ether (iii) Bis (2-methoxyethyl) ether
(iv) Phenetole (v) p-Nitrophenetole (vi) tert-Butyl methyl ether

Explanation

To write the structural formulas for the given compounds, we will follow a systematic approach for each one.

### Step-by-Step Solution:

**(i) Di-isopropyl ether:**
1. Identify the isopropyl group, which has the formula: \( \text{(CH}_3)_2\text{CHO} \).
2. Since it is di-isopropyl ether, we will have two isopropyl groups connected by an oxygen atom.
3. The structural formula can be represented as:
...
