Question

The bond between the two atoms by mutual sharing of electron so as to complete their octets or duplets gives:
a.) Covalent compound
b.) Metallic compound
c.) Ionic compound
d.) None of above

Answer 1

A chemical bond shaped between two particles by common sharing of electrons between them to finish their octets or duplets, is known as covalent bond and the quantity of electrons contributed by every atom is known as covalence.

Complete step by step answer:
The Covalent bond was first proposed by Lewis in 1916. The bond framed between the two atoms by common sharing of electrons in order to finish their octets or duplets (in the event of components having just one shell) is called covalent bond or covalent linkage. In chemistry, in the Covalent bond the interatomic linkage that outcomes from the sharing of an electron pair between two atoms. The coupling emerges from the electrostatic attraction of their nuclei for similar electrons. A covalent bond between two similar atoms is a nonpolar covalent bond while it is polar between two diverse particles having various electronegativity.

Properties of Covalent Compounds:
1. Generally, covalent compounds exist in the fluid or vaporous state at room temperature because of the size of intermolecular powers.
2. Covalent compounds consist of low melting and boiling points.
3. Covalent compounds are commonly helpless transmitters of power since they don't contain free electrons or particles to direct power.
4. They are dissolvable in non-polar solvents like benzene yet typically insoluble in water.
So, the correct answer is “Option A”.

Note: As the Octet rule indicates that during the arrangement of a covalent bond, the atoms accomplish an inert gas electronic setup (valence shell contains 8e– or shell is totally filled). An atom may achieve this configuration by picking up, losing or imparting electrons to different particles
