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: -The few carbon-containing compounds not classified as organic include carbides, carbonates, and cyanides.
Detailed explanation-4: -H2O is not an organic compound. You can tell by the chemical formula that the compound is made up of hydrogen (H) and oxygen (O). There is no carbon (C) in this compound, so it’s not an organic compound.
