Chapter U2.4, Problem 1TAI

Interpretation Introduction

Interpretation:

The bonding between the atoms in a molecule must be explained.

Concept introduction:

There are different types of bonds of atoms in a molecule which are ionic or electrovalent, covalent and coordinate covalent.

Explanation of Solution

In case of ionic bonds between atoms there is electrostatic interaction or complete transfer of electrons takes place from electropositive to electronegative atom whereas in case of covalent bonds there is equal sharing of electrons.

The bonding in methane molecule is shown for example in which carbon atom and hydrogen atom are bonded with each other using single bonds.

  

Here, C and H are forming covalent bonds because each bond shares 2 electrons between C and H atoms.

Generally, the bonds formed between two non-metals are covalent and bond formed between a metal and a non-metal is ionic in nature.

The example of an ionic bond is NaCl here, Na is electropositive and Cl is electronegtive. Also, Na is metal and Cl is non-metal.
