Question

what is polar and non polar covalent compounds

Answer 1

HERE IS YOUR ANSWER

(Nonpolar covalent bonds )are a type of bond that occurs when two atoms share a pair of electrons with each other. These shared electrons glue two or more atoms together to form a molecule. Like children who share toys, atoms involved in a nonpolar covalent bond equally share electrons. An example of a nonpolar covalent bond is the bond between two hydrogen atoms because they equally share the electrons. 

(Polar covalent bonding) is a type of chemical bond where a pair of electrons is unequally shared between two atoms. In a polar covalent bond, the electrons are not equally shared because one atom spends more time with the electrons than the other atom. In polar covalent bonds, one atom has a stronger pull than the other atom and attracts electrons.

Answer 2

hey,

here the ans is ........
 
the greater the electro negativity difference,the more ionic the bond is.Bonds that are partly ionic are called Polar Covalent Bonds...
eg: NH₃
      H₂O

Non Polar Covalent Bonds,with equal sharing of the bond electrons,arise when the electronegitives of the two atoms are equal...
eg: CH₄
      C₂H₂

hope my ans helps u frnd...

plz...mark my ans as brainliest ans..

THANK YOU ^-^
