Explanation

To solve the problem of what products are formed when isobutyl bromide is treated with absolute ethyl alcohol in dry ether, we can follow these steps:

### Step 1: Identify the Reactants
The reactants in this reaction are isobutyl bromide (C4H9Br) and absolute ethyl alcohol (C2H5OH).

### Step 2: Understand the Reaction Conditions
The reaction takes place in dry ether, which is a non-polar solvent that can facilitate the reaction between the alkyl halide and the alcohol.

### Step 3: Mechanism of Reaction
Isobutyl bromide is a primary alkyl halide. When it reacts with ethyl alcohol, it undergoes a nucleophilic substitution reaction. The hydroxyl group (-OH) of ethyl alcohol acts as a nucleophile and attacks the carbon atom bonded to the bromine in isobutyl bromide.

### Step 4: Formation of Isobutyl Magnesium Bromide
In the presence of dry ether, isobutyl bromide can react to form isobutyl magnesium bromide (C4H9MgBr) through a Grignard reaction. This occurs because the dry ether can stabilize the Grignard reagent.

### Step 5: Reaction of Isobutyl Magnesium Bromide with Ethyl Alcohol
When isobutyl magnesium bromide is treated with ethyl alcohol, it reacts to form isobutyl alcohol (C4H10O) and magnesium bromide (MgBr). The Grignard reagent reacts with the alcohol, leading to the formation of the corresponding alcohol and releasing magnesium bromide as a byproduct.

### Final Products
Thus, the final products formed from the reaction of isobutyl bromide with absolute ethyl alcohol in dry ether are isobutyl alcohol and magnesium bromide.

### Summary of Products:
1. Isobutyl alcohol (C4H10O)
2. Magnesium bromide (MgBr)
