Give reason for the following :
'In acylium ion, the structure `R-C -= O^(oplus)` is more stable than `R- overset(oplus) C=O`.

Explanation

To explain why the acylium ion structure \( R-C \equiv O^{+} \) is more stable than \( R^{+} - C=O \), we can analyze the electronic structure and stability of both forms. Here’s a step-by-step breakdown:

### Step 1: Understanding the Structures
- The acylium ion can be represented in two forms:
1. \( R-C \equiv O^{+} \) (Structure 1)
2. \( R^{+} - C=O \) (Structure 2)

### Step 2: Analyzing Electron Count
