Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which substance is an inorganic molecule?
A
starch
B
DNA
C
water
D
fat
Explanation: 

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: -Inorganic substances are a group of chemicals that contain no carbon. Examples include ammonia, hydrogen sulfide, all metals, and most elements (such as calcium).

Detailed explanation-3: -H2O means each molecule of water contains two atoms of hydrogen (H) joined to one atom of oxygen (O). In order for something to be organic-as in alive-it needs carbon. So water, by definition is inorganic.

Detailed explanation-4: -Inorganic compounds essential to human functioning include water, salts, acids, and bases. These compounds are inorganic; that is, they do not contain both hydrogen and carbon.

Detailed explanation-5: -Because water is two hydrogen molecules and one oxygen molecule, by definition it is then an inorganic compound, and cannot be organic.
