Question

4. Keeping VSEPR model in mind, draw the Lewis Structures for ethanol (C2H5OH) and dimethyl ether (CH3OCH3). Determine the electron pair geometry and molecular geometry around the oxygen atom in each.

Answer 1

Answer:

Both the oxygen atom in both compounds have a Tetrahedral bent geometry.

Explanation:

In dimethyl ether and ethanol each carbon has four valence electrons. Oxygen has six valence electrons and hydrogen has one valence electron.

The electron pair and molecular geometry around both the oxygen atom in each are Tetrahedral bent.

Answer 2

Answer:

Both ethanol and diethyl ether have tetrahedral geometry.

Explanation:

VSEPR Rules are

1. Identify the central atom.

2. Count its valence electrons.

3. Add one electron for each bonding atom.

4. Add or subtract electrons for charge

5. Divide the total of these by 2 to find the total.

number of electron pairs.

6. Use this number to predict the shape.
