Verified step by step guidance1
Identify the elements present in perchloric acid (HClO_4): hydrogen (H), chlorine (Cl), and oxygen (O).
Recall that perchloric acid consists of hydrogen bonded to the polyatomic ion perchlorate (ClO_4^-), which is a group of nonmetals bonded covalently.
Understand that molecular compounds are typically formed between nonmetal atoms sharing electrons through covalent bonds, resulting in discrete molecules.
Recognize that ionic compounds form between metals and nonmetals, where electrons are transferred, creating ions held together by electrostatic forces.
Since HClO_4 is composed of nonmetals and forms molecules with covalent bonds, classify it as a molecular compound.
