Line bond structure

The line bond structure of the molecule represents the covalent bond between two atoms by a line and the atoms are represented by their respective chemical symbol.

Line bond structure of the following

a) CHCl₃

In chloroform, carbon is the central atom that has four valence electrons. Its valency is satisfied as it forms three bonds with chlorine and one bond with hydrogen. The nonbonding electrons are present in chlorine is represented as:

Chloroform

b) H₂S

In hydrogen disulfide sulfur is the central atom and its valency is six. So it forms two bonds with two hydrogen and the remaining four electrons are present on sulfur as nonbonding electrons represented as:

Hydrogen disulfied.

c)

CH₃NH₂

In methylamine, the central atom is carbon its valency is four. The valency of carbon is satisfied by forming three bonds with hydrogen and the fourth bond is formed with group. The nonbonding electrons are present in nitrogen.

Methylamine

d) CH₃Li

In methyl lithium central atom is carbon its valency is 4. It is bonded to three hydrogen atoms and the fourth bond is formed with lithium as shown:

Methyllithium
