Detailed explanation-1: -Water is definitely an inorganic compound (dihydrogen oxide) and methyl alcohol is definitely an organic compound. As with all empirical classification schemes, the distinction is not particularly clear when the lower molecular weight substances are considered.

Detailed explanation-2: -Water (H2O) has no carbon; then, it is not an organic compound. Sodium chloride has neither carbon nor hydrogen; then, it is not an organic compound. Generally, gases, and mineral salts (inorganic substances found in soil, or bodies of water or watercourses) are not organic.

Detailed explanation-3: -Organic compounds are large class of chemical compounds in which one or more atoms of carbon are covalently linked to atoms of other elements, most commonly hydrogen, oxygen and nitrogen. Thus amongst the given options, ammonia is not an organic compound.

Detailed explanation-4: -Because water is two hydrogen molecules and one oxygen molecule, by definition it is then an inorganic compound, and cannot be organic.

Detailed explanation-5: -Water in chemistry terms is H2O, one oxygen atom linked to 2 hydrogen ones, no carbon at all so not organic. Actually it is inorganic in chemistry terms.
