Detailed explanation-1: -Water is an inorganic compound with the chemical formula H 2O. It is a transparent, tasteless, odorless, and nearly colorless chemical substance, and it is the main constituent of Earth’s hydrosphere and the fluids of all known living organisms (in which it acts as a solvent).
Detailed explanation-2: -The chemical formula for water is H2O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms. Thus, water is a compound.
Detailed explanation-3: -Water is a Polar Covalent Molecule Water (H2O), like hydrogen fluoride (HF), is a polar covalent molecule. When you look at a diagram of water (see Fig. 3-2), you can see that the two hydrogen atoms are not evenly distributed around the oxygen atom.
Detailed explanation-4: -Water is a molecule because it contains molecular bonds. Water is also a compound because it is made from more than one kind of element (oxygen and hydrogen). If you like, you can say that water is a molecular compound.
Detailed explanation-5: -In the past, some schools taught that molecules consisted of atoms bonded via covalent chemical bonds, while compounds were formed via ionic bonds. The hydrogen and oxygen atoms in water are covalently bonded, so under these older definitions, water would be a molecule but not a compound.
