Complete the following reactions:
`2Me_(3)C--Br` `overset (Ag_(2)CO_(3)) underset (Delta) rarr` (A)

Explanation

To complete the reaction given in the question, we will follow these steps:

### Step 1: Formation of Carbocation
The reaction begins with the compound \( 2 \text{Me}_3\text{C-Br} \) (where Me represents a methyl group, \( \text{CH}_3 \)). When this compound reacts with silver carbonate (\( \text{Ag}_2\text{CO}_3 \)) under heat (\( \Delta \)), the bromine atom is displaced, leading to the formation of a carbocation.

**Reaction:**
\[ 2 \text{Me}_3\text{C-Br} + \text{Ag}_2\text{CO}_3 \rightarrow 2 \text{Me}_3\text{C}^+ + 2 \text{AgBr} \]
