Write the main product (s) in each of the following reaction :
(i) `CH_(3) - underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-O-CH_(3)+HIrarr`
(ii) `CH_(3) - CH = CH_(2) underset((ii)3H_(2)O_(2)//OH^(-))overset((i)B_(2)H_(6))rarr`
(iii) `C_(6)H_(5) - OH underset((ii)CO_(2),H^(+))overset((i)aq.NaOH)rarr`

Explanation

Let's break down the reactions step by step to identify the main products.

### (i) Reaction of Tertiary-butyl methyl ether with HI

1. **Identify the reactants**: The reactant is tertiary-butyl methyl ether, which can be represented as \( CH_3 - C(CH_3)_3 - O - CH_3 \).
2. **Protonation of the ether**: When HI is added, the ether oxygen gets protonated, forming a protonated ether.
3. **Cleavage of the ether**: The bond between the oxygen and the less sterically hindered alkyl group (methyl group) breaks, leading to the formation of methyl iodide (\( CH_3I \)) and tertiary butyl alcohol (\( (CH_3)_3COH \)).
4. **Products**: The main products are:
