Question

Write a note on properties and uses of covalent compounds.

Answer 1

Hint: Before writing a short note on the properties and uses of covalent compounds we should be knowing what a covalent compound is. A covalent compound is basically a molecule which is formed by covalent bonds. This means that the atoms share one or more pairs of valence electrons.

Step by step answer:
Here is a short list of the main properties of the covalent compounds:
- First, most of the covalent compounds have relatively low melting and boiling points.
- Second, the covalent compounds usually have lower enthalpies of fusion and vaporization as compared to the ionic compounds.
- Third, covalent compounds tend to be more flammable as compared to the ionic compounds.
- Fourth, the covalent compounds are soft and brittle in nature. And lastly, when dissolved in water covalent compounds do not conduct electricity.
Here are the examples of some of the valuable covalent compounds that we use in our daily life:
- First, Carbon Dioxide, it is a covalent compound which is used in soft or cold drinks and some other fluids as well and we use it in daily life.
- Second, Hydrogen Monoxide, it is the normal or original or pure water which we drink every day in our daily life and it is very important for survival.
- Third, Ammonia is also a covalent compound which is used in soaps, detergents, washing bars and some other cleaning liquid in daily life.
- Fourth, vinegar or Acetic Acid, it is also a covalent compound usually used in cooking in daily life.
- Fifth, cooking gas or propane, is used by us in day to day life for the Lightning of stoves, cooking food. It is a covalent compound.
- Sixth, Sugar or Sucrose is another covalent compound which is used in our daily life in various food items like sweets, tea etc.

Note: Covalent compounds have very weak forces of attraction between their binding molecules. So, very less amount of energy is required to break the force of bonding. So, they have very low melting and boiling points.
