Both of the atoms need 1 electron each to attain stability. $\ce{HCl}$ and $\ce{HF}$ are very similar with one covalent bond that pulls the hydrogen electron towards their "shared" region, exposing the hydrogen atom as a positive end of this permanent dipole. First of all, the main thing you must realise is that no compound is purely covalent or ionic. A) How HCl is a polar covalent compound:-HCl is called covalent because both hydrogen and chlorine atoms share one electron with each other to satisfy their respective valence shells and hence they form covalent bond. How long will the footprints on the moon last? HCl gas is a covalent molecular compound, HCl in water dissociates to form H+(aq) + Cl-How many covalent bond does HCI contains? Think of a bond as two nuclei competing for a couple of electrons. Unless the bond connects two atoms of the same element, as in H 2 , there will always be one atom that attracts the electrons in the bond more strongly than the other atom does, as in HCl, shown in Figure \(\PageIndex{1}\). Although we defined covalent bonding as electron sharing, the electrons in a covalent bond are not always shared equally by the two bonded atoms. Therefore it also needs 1 electron to complete its octet. Hydrogen has only 1 electron so it cannot give it. HCL is covalent in gaseous state but ionic in an aqueous state. hcl is a covalent or ionic || polar and nonpolar covalent bonds. Therefore it needs 1 electron to complete its duplet. HCl is formed by Hydrogen and Chlorine. Question = Is SCN- polar or nonpolar ? When it is dissolved in Polar solvent H2O, it is ionized into its constituent ions H+ & Cl-. HCL is covalent in gaseous state but ionic in an aqueous state. HCl is definately covalent. Both can create secondary dipole bonds to adjacent molecules of the same type. HCI would contain two (2) covalent … HCl is a polar covalent compound. Elements form bonds to attain stability. Q.1) Why is Hydrochloric acid a covalent compound? hence it posseses ionic character as well. Because, both the atoms share the elect… Why is HCl, being a covalent compound, made by using the crisscross method of valency?AnsweR:HCl is a covalent compound. A small electronegativity difference leads to a polar covalent bond. My question is why this definition excludes compounds such as $\ce{HCl}$? Chlorine has 7 valence electrons.
