For Et2AlX (X = PPh2–, Ph–, Cl– –and H–)...
Explanation:

Et2AlX compounds are organometallic compounds that are commonly used as catalysts in organic reactions. These compounds have a tendency to form dimeric structures, where two molecules of the compound are bonded together. The order of this tendency towards dimerization follows the order of the X group attached to the Et2Al.

The X group can be PPh2, Ph, Cl, or H. Let's look at each of these groups individually:

1. PPh2: This is the triphenylphosphine group, which is a bulky and sterically hindered group. This group reduces the tendency towards dimerization because it takes up more space and makes it difficult for two molecules to come close enough to form a dimer.

2. Cl: The chlorine group is a small and electronegative group. It has a moderate tendency towards dimerization because it can form weak hydrogen bonds with neighboring molecules.

3. H: The hydrogen group is the smallest and least polar group. It has a strong tendency towards dimerization because it can form strong hydrogen bonds with neighboring molecules.

4. Ph: The phenyl group is a large and non-polar group. It has the strongest tendency towards dimerization because it can form strong pi-pi interactions with neighboring molecules.

Based on these factors, the order of the tendency towards dimerization follows the order of the X group attached to the Et2Al. Therefore, the correct answer is option 'C', where the order is Ph, H, Cl, PPh2.
