The characteristics of the molecules depend upon the various parameters. It is also used in the production of plastics. Like in the case of HCN, although the shape of the molecule is symmetric (linear), the molecule is polar due to the difference in electronegativity of its atoms. Ch. Greater the value of the dipole of a molecule more is its polarity. Greater the difference between the electronegativity of both atoms more is the polarity of that molecule. Whereas the symmetrically shaped molecule is nonpolar only if the electronegativity of atoms is equal. If we talk about the chemical composition of hydrochloric acid, it consists of 1 hydrogen molecule and 1 chlorine molecule.
The difference in electronegativity is directly proportional to the polarity of the molecule. This is because higher electronegative atom attracts the charge across its side and becomes a negative pole and in return, another atom becomes a positive pole.
