Why does NaCl have ionic bonding whereas HCL has covalent bonding?
Sodium chloride is an ionic compound as sodium is a metal and chlorine is a non-metal but hydrogen chlorine is a covalent compound as hydrogen and chlorine both are non metals. Hence, the correct answer is option B.
Is HCL a covalent or Electrovalent compound?
Potassium chloride is an electrovalent compound, while hydrogen chloride is a covalent compound, But, both conduct electricity in their aqueous solutions.
Does HCL have Electrovalent bond?
Covalent bond is present in HCL. It is a strong bond but weaker than Electrovalent bond because there is no transfer of electron take place.
Why HCl is covalent?
if you see HCl compound, both are non-metals and non-metals don’t have tendency to loose electrons, so both the elements H and Cl share their electrons to complete their octet and make them stable. Sharing of electrons is possible in covalent bonding, so that is why HCl is a covalent compound.
Why NaCl is solid and HCl is gas?
Chlorine (Cl2) is a gas at room temperature, but sodium chloride(NaCl) is a solid at room temperature. It forms a giant lattice due to the strong ionic force of attraction between the similar molecules,(NaCl – NaCl attraction is strong) so they require huge amount of energy(at higher temperature) to break those forces.
Is NaCl a covalent bond?
For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl. In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals….Table 2.11.

Why HCl is covalent bond?
Consider the hydrogen chloride (HCl) molecule. Chlorine has a higher electronegativity than hydrogen, but the chlorine atom’s attraction for electrons is not sufficient to remove an electron from hydrogen. Consequently, the bonding electrons in hydrogen chloride are shared unequally in a polar covalent bond.
Is HCl covalent?
In its gaseous state, HCl is a covalently bonded molecule but exhibits considerable polarity. In aqueous solution, the molecules ionizes to produce H+ and Cl- in The presence of water acting as a Base. The ability to ionize also makes it useful as an electrolyte.
Is nacl a covalent bond?
Is HCl a covalent or ionic compound?
HCl, is a covalent compound, as the hydrogen and chlorine atoms share one electron, and hydrogen is acting as a non-mental, so the bond is formed between two non-metals. However, when HCl is in an aqueous solution, the compound takes on more ionic characteristics, such as the ability to conduct electricity in…
What is an electrovalent bond in chemistry?
Electrovalent Bond Electrovalent bonds are produced when electrons are transferred from atoms of one element to atoms of another element, producing positive and negative ions. The bond which is formed by the transfer of electrons between the atoms is called electrovalent bond or ionic bond.
Why does HCl conduct electricity in aqueous solution?
However, when HCl is in an aqueous solution, the compound takes on more ionic characteristics, such as the ability to conduct electricity in water, because it is a polar covalent compound and as such ionizes when added to water.
Does HCL have a positive or negative dipole?
As such, the chlorine will have a negative dipole, and the hydrogen will have a positive dipole. When hydrogen chloride is added to water, becoming HCl (aq), the positive dipole of the HCl molecules (hydrogen), will attract to the negative dipoles of the H2O molecules (oxygen).
