2. 3.1.1 define bond energy; K
bond energy (E) or bond enthalpy (H) is the
measure of bond strength in a chemical bond.
Bond energy is denoted by ‘E’.

3. 3.1.2 relate bond energy with bond strength
Bond strength is always directly proportional to the bond energy or viceversa.

4. 3.1.3 define bond length
Generally, the length of the bond between two atoms is approximately the sum of the covalent radii of the two atoms.
Bond length is reported in picometers

5. Relate bond strength and bond distance
Bond strength is invesely proportional to the bond length and viceversa.
The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length
