Predict whether each of the following compounds is molecular or ionic: (b) CH3OCH3

Key Concepts

Molecular Compounds

Molecular compounds are formed when two or more nonmetals share electrons through covalent bonds. They typically have low melting and boiling points and can exist in various states (solid, liquid, gas) at room temperature. The presence of specific elements, such as carbon and hydrogen, often indicates a molecular compound.

Ionic Compounds

Ionic compounds are formed when metals transfer electrons to nonmetals, resulting in the formation of charged ions that attract each other due to electrostatic forces. These compounds usually have high melting and boiling points and are often soluble in water. The presence of a metal and a nonmetal in a compound typically suggests it is ionic.

Chemical Structure and Bonding

The chemical structure of a compound determines its classification as molecular or ionic. In the case of CH3OCH3 (dimethyl ether), the structure consists of covalent bonds between carbon, hydrogen, and oxygen atoms, indicating it is a molecular compound. Understanding the arrangement of atoms and the types of bonds formed is crucial for predicting the nature of a compound.
