What is the van't Hofffactor for a compound which undergoes tetramerisation in an organic solvent ?

Explanation

To find the van't Hoff factor (i) for a compound that undergoes tetramerization in an organic solvent, we can follow these steps:

### Step 1: Understand Tetramerization
Tetramerization refers to the process where four molecules of a substance combine to form a single molecule. If we denote the original molecule as A, after tetramerization, it will form A4.

### Step 2: Initial and Final Moles
Initially, we have 1 mole of A and 0 moles of A4. After complete tetramerization, all of the 1 mole of A will convert into A4.
