0The compounds like urea, sugars, fats, oils, dyes, proteins vitamins etc., which were isolated directly or indirectly from living or indirectly from living organism such as animals and plants were called organic compounds. The branch of chemistry which deals with the study of these compounds is called Organic Chemistry.
Hydrogen Molecules:
This is the simplest molecule formed by sharing of electrons. The atomic number of hydrogen is 1 and it has only one electron is its outermost K shell. It required only one more electron to complete the K shell. So, when two hydrogen atoms approach each other, the single electron of both the atoms form a shared pair.
Chlorine Molecule:
Each chlorine atom has seven electrons in its outermost shell. When the two chlorine atoms come close together, an electron of both the atoms is shared between them.
Nitrogen Molecule:
Nitrogen atom has five electrons in its valence shell. In the formation of a nitrogen molecule, each of the following atoms provide three electrons to form three electrons pairs for sharing. Thus, a triple bond is formed between two nitrogen atoms.
