Question

How to find whether a given compound is polar or non polar in nature ?
SOMEONE ANSWER FAST AND CLEARLY , PLEASEEEE ?!!!!

Answer 1

There are some basic rules for finding weather a compound polar or not are as following

1. When the resulting dipole is 0

Eg- bond between identical atoms F-F

2. If the resultant dipole is not zero then the compound on following parameters

I) If the compound is is symmetrical than dipole moment is zero

... Eg- Co2 O-C-O (molecule is non-polar)

ii) if the molecule is unsymmetrical then the dipole is not zero

Eg - H2O has bent structure hence there is some resultant dipole hence the molecule is polar.

For molecules like Ccl4 the structure is tetrahedral hence all the chlorine molecules have same electronegativity hence the resultant dipole moment is zero HENCE MOLECULE IS NON POLAR

Answer 2

Simply, a polar covalent compound is one in which there is unequal sharing of electrons to form bonds.
A non-polar covalent compound is one in which there is equal sharing of electrons to form bonds.
Example of polar covalent compound:- H2O (water) in which each hydrogen atom acquires the duplet while the oxygen atom acquires the octet.
Example of non-polar covalent compound:- Cl2 (chlorine molecule) in which two chlorine atoms each acquire the octet.

I hope this simple answer helps...
