The total number of single, double, and triple covalent bonds present in Lewis structure of molecule has to be chosen from the given options. Concept Introduction: Bonds are formed between the atoms and it is the force that holds the atom together. There are mainly two types of bonds and they are ionic bond and covalent bond. Ionic bonds are formed between different elements (metal and nonmetal). Ionic bonds are formed by giving and accepting valence electrons. Covalent bonds are formed between two nonmetals. They can be of same atoms or different atoms also. Covalent bonds are formed by sharing of valence electrons between two atoms. Covalent bond in which one pair of electrons is shared between two atoms is a single covalent bond. Covalent bond in which two pairs of electrons is shared between two atoms is a double covalent bond. Covalent bond in which three pairs of electrons is shared between two atoms is a triple covalent bond. Double bond and triple bond are known together as multiple bonds. Triple covalent bond is three times strong than single covalent bond between two same atoms. A single line between two atoms is used to denote a single covalent bond, two lines for a double covalent bond and three lines for a triple covalent bond.

Interpretation Introduction

Interpretation:

The total number of single, double, and triple covalent bonds present in Lewis structure of molecule has to be chosen from the given options.

Concept Introduction:

Bonds are formed between the atoms and it is the force that holds the atom together. There are mainly two types of bonds and they are ionic bond and covalent bond.

Ionic bonds are formed between different elements (metal and nonmetal). Ionic bonds are formed by giving and accepting valence electrons. Covalent bonds are formed between two nonmetals. They can be of same atoms or different atoms also. Covalent bonds are formed by sharing of valence electrons between two atoms.

Covalent bond in which one pair of electrons is shared between two atoms is a single covalent bond. Covalent bond in which two pairs of electrons is shared between two atoms is a double covalent bond. Covalent bond in which three pairs of electrons is shared between two atoms is a triple covalent bond. Double bond and triple bond are known together as multiple bonds. Triple covalent bond is three times strong than single covalent bond between two same atoms.

A single line between two atoms is used to denote a single covalent bond, two lines for a double covalent bond and three lines for a triple covalent bond.
