Solution

The correct option is B

The electrons are completely transferred from one atom to another.


The chemical bond that is formed between two combining atoms by mutual sharing of one or more pairs of electrons is called a covalent bond. Covalent bonds can be polar or non-polar. A covalent bond between two similar atoms or dissimilar atoms which have little or zero electronegativity difference is called a non-polar covalent compound. The covalent compound is said to be polar when the shared pair of electrons are not at an equal distance between the two atoms. For example, two chlorine atoms combine together by the sharing of electrons to form a chlorine molecule and a covalent bond is formed between the two chlorine atoms.
