methanol (CH4O)
it is Diphosphorus pentaoxide but it exists as dimer P4O10.
Caffeine is a compound and so is a pure substance.
Gold is a pure substance (element), water is a compound, steel is an alloy, and air is a mixture of gases.
HCIO4 is an ionic compound.
No, perchloric acid (HClO₄) is not an ionic compound; it is molecular (covalent). Why: It’s made of nonmetals (H, Cl, O) → they share electrons → covalent bonds. As a pure substance, it exists as molecules, not a lattice of ions. But here’s the key detail: In water, perchloric acid is a strong acid, so it ionizes completely into H⁺ and ClO₄⁻. That means it behaves like an ionic solution, but the compound itself is still molecular. Final answer: Perchloric acid is molecular, not ionic.
A Molecular Substance or Compound.
it is Diphosphorus pentaoxide but it exists as dimer P4O10.
The identity of a substance (chemical compound) is defined by his chemical formula and molecular structure.
Caffeine is a compound and so is a pure substance.
Gold is a pure substance (element), water is a compound, steel is an alloy, and air is a mixture of gases.
Since Oxygen exists in combined state in nature, it is termed as a molecular element and Sucrose is a molecule of Carbon, Hydrogen and Oxygen with no charge on it, hence it is considered a molecular compound.
Carbon dioxide is a molecular compound with the formula CO2
The representative unit in a molecular compound is a molecule, which consists of two or more atoms bonded together. This unit represents the smallest particle of the compound that retains the chemical properties of the substance.
Matter with a definite composition is a pure substance, such as an element, molecule, molecular compound, or ionic compound.
For an element, it would be an atom. For a molecular substance, it would be a molecule. If it is an ionic compound, it would be a formula unit.
