Explain the following: (a) Covalent compounds are generally gases or liquids or soft solids. (b) Covalent compounds have low melting point and boiling point. (c) Non-polar covalent compounds are insoluble in water. (d) Polar covalent compounds are good conductors of electricity. Chemistry. Frank Chemistry - II. Standard X.
Oct 22, 2019 · H 2 O, HI, HCl, NH 3. Non-polar covalent bond – Formed by identical atoms. Eg.Cl 2, O 2, N 2 , etc. Covalent bonds formed between atoms of the same kind are usually non-polar and the shared electrons are equidistant from both atomic nuclei.
Oct 30, 2019 · So for polarity to occur in a molecule, you have to have two different elements at a minimum, 02:51. and the difference between their electronegativities has …
Chlorine, Iron, Aluminium, Iodine, Carbon and Sulphur Powder. Compounds – They are also pure, but can be broken down in constituents. Potassium Chloride …
A polar molecule always contains polar bonds, but some molecules with polar bonds are nonpolar. Polar Molecule. A molecule in which the bond dipoles present do not cancel each other out and thus results in a molecular dipole.(see below).
Polar Molecule. A molecule in which the bond dipoles present do not cancel each other out and thus results in a molecular dipole.(see below). Cancellation depends on the shape of the molecule or Stereochemistry and the orientation of the polar bonds. Molecular Dipole. A result of the bond dipoles in a molecule.
A bond between 2 nonmetal atoms that have the same electronegativity and therefore have equal sharing of the bonding electron pair. Example: In H-H each H atom has an electronegativity value of 2.1, therefore the covalent bond between them is considered nonpolar.
Example: In H-Cl, the electronegativity of the Cl atom is 3.0, while that of the H atom is 2.1. The result is a bond where the electron pair is displaced toward the more electronegative atom.
The result is a bond where the electron pair is displaced toward the more electronegative atom. This atom then obtains a partial-negative charge while the less electronegative atom has a partial-positive charge.This separation of charge or bond dipole can be illustrated using an arrow with the arrowhead directed toward the more electronegative atom.
The Greek letter delta indicates "partially". Within a molecule each polar bond has a bond dipole. A polar molecule always contains polar bonds, but some molecules with polar bonds are nonpolar. A molecule in which the bond dipoles present do not cancel each other out and thus results in a molecular dipole.(see below).

The non-polar covalent bond is a covalent bond in which the difference in electronegativity between bonded atoms is less than 0.5 . Polar covalent bonding is a type of chemical bond where a pair ...
Polar covalent bonds are charged (positive as well as negative poles), whereas non-polar covalent bonds are not charged.
What Are Polar And Non Polar Covalent Compounds? The polar covalent bond is a type of covalent bond formed between two non-identical atoms. Since the two atoms differ in their capacity to attract the shared electron pair unequal sharing of electrons results.
Due to the unequal sharing of electrons, fractional positive and negative charges are developed on the bonded atoms and the bond is said to be polar.
The non-polar covalent bond is a covalent bond in which the difference in electronegativity between bonded atoms is less than 0.5. Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared between two atoms due to the difference in their electro-negativities. These compounds are called polar covalent compounds.
