Answer:
D: H2O
Explanation:
A molecular compound (also known as a covalent compound) is defined as a compound where atoms share electrons. This type of bond is called a covalent bond.
Molecular compounds form between non-metal elements.
- H2O is made up of non-metal atoms, Hydrogen and Oxygen. Therefore, the bonds are covalent and the compound is a molecular compound.
In contrast, when bonds are formed between a metal and a non-metal, an ionic compound is formed.
- NaOH - Sodium (metal), Oxygen (non-metal), and Hydrogen (non-metal); Ionic compound
- K2O - Potassium (metal) and Oxygen (non-metal); Ionic compound
- KCL - Potassium (metal) and Chloride (non-metal); Ionic compound
