Question

Hcl is called a polar covalent compound?

Answer 1

HCl is a polar covalent compound because in this H+ is a proton having electron affinity and having the tendency to gain the electron but Cl- is act like an anion and having tendency to donate the electron and Cl- is a electronegative atom and as the H+ comes close to Cl- anion then negative charge spreads and polarity begins according to Fazan's Rule and due to this two shared pair electrons of Cl- make the covalent bond with H+ (both the electrons in covalent bond is from Cl- atom. HCl is also called it as hetro-atomic molecule. .........

Answer 2

Hello friend!!

What is a polar covalent compound?
The compound formed between two non metals is covalent, but it is polar, when there is a huge electronegativity difference between the atoms of the constituent non metals.

In HCl, electronegativity of H is 2.1 and that of Cl is 3. The difference is huge, so Chlorine, being more electronegative, tends to attract the shared pair of electron towards itself. This results in the development of a slight negative charge on the side of Chlorine and a slight positive charge on the side of hydrogen. Thus, the molecule becomes dipole, hence HCl is a polar covalent compound.
