Which of the following is considered a molecular compound

A:NaOH

B:K2O

C:KCL

D:H2O

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

D:H2O is a molecular compound
