explain bond parameter
Answers
Answer:
Covalent bonds can be characterized on the basis of several bond parameters such as bond length, bond angle, bond order, and bond energy (also known as bond enthalpy). These bond parameters offer insight into the stability of a chemical compound and the strength of the chemical bonds holding its atoms together.

Bond Parameters
Bond Order
The bond order of a covalent bond is the total number of covalently bonded electron pairs between two atoms in a molecule. It can be found by drawing the Lewis structure of the molecule and counting the total number of electron pairs between the atoms in question.
Single bonds have a bond order of 1.
Double bonds have a bond order of 2.
Triple bonds have a bond order of 3.
Note: If the bond order of a covalent bond is 0, the two atoms in question are not covalently bonded (no bond exists).
Examples
The bond order of the carbon-hydrogen bond in C2H2 (ethyne/acetylene) is 1 and that of the carbon-carbon bond is 3.
The bond order of the oxygen-oxygen bond in an O2 molecule is 2.
In a carbon monoxide molecule, the carbon-oxygen bond has a bond order of 3, as illustrated in the Lewis structure provided below.
The Bond Order in Carbon Monoxide is 3
Since the nitrate ion is stabilized by resonance, the bond order of the nitrogen-oxygen bond is 4/3 or 1.33. It is calculated by dividing the total number of nitrogen-oxygen bonds (4) by the total number of covalently bonded nitrogen-oxygen groups (3)
