Question 1:
What is the Lewis structure of dimethyl ether?
Answer:
The Lewis structure of dimethyl ether is a representation of the molecule’s bonding and electron arrangement. It consists of a central oxygen atom double-bonded to two methyl groups. Each methyl group has three hydrogen atoms bonded to the carbon atom. The Lewis structure shows the lone pairs of electrons on the oxygen atom and the carbon atoms in the methyl groups.
Question 2:
How many valence electrons are in dimethyl ether?
Answer:
Dimethyl ether has a total of 20 valence electrons. Oxygen has six, each carbon has four, and each hydrogen has one valence electron. The double bond between the oxygen and each carbon contributes two electrons each, and the lone pairs on the oxygen and carbon atoms contribute two electrons each.
Question 3:
What is the molecular shape of dimethyl ether?
Answer:
Dimethyl ether has a tetrahedral molecular shape. The oxygen atom is at the center with the two methyl groups bonded to it. The lone pairs on the oxygen atom push the methyl groups apart, resulting in a tetrahedral electron pair geometry and molecular shape.
