What is the properties of covalent bond?
Covalent compounds generally have much lower melting and boiling points that ionic compounds.
Covalent compounds are soft and squishy.
Covalent compounds tend to be more flammable that ionic compounds.
Covalent compounds don't conduct electricity in water.
Covalent compounds aren't usually very soluble in water.
Answer The larger the difference in electronegativity the more ionic properties a bond is said to have. The smaller the difference in electronegativity the more covalent properties a bond is said to have The magic number is 1.7 , if electronegativity (EN) difference is less than 1.7 then it is covalent. if it is more, then its ionic bond.
A coordinate covalent bond is when two atoms have a covalent bond where the two electrons that are shared by the atoms in the bond come from only one of the atoms. This bond does not have any different properties than a polar covalent bond it is just named differently to show that the electrons came from an atom with a lone pair. This occurs when a Lewis base donates electrons to a Lewis acid.
A polar covalent bond is not different from a covalent bond, because a polar covalent bond is a covalent bond. Polar covalent bonds are a category of covalent bonds which are distinguished from other covalent bonds by larger bond dipole moments, caused by a greater average electron density near the more electronegative element that is so bonded.
Polar covalent bond and Non-polar covalent bond are the two types of covalent bonding where the sharing of electrons occurs. The difference between the two is that polar covalent bond is the sharing of electrons between two different elements while non-polar covalent bond is the sharing of two like elements.
