Answer» (i) It is the number of covalent bonds holding the atoms in the molecule. Example: If the bond is formed by the sharing of two electron pairs, then the bond order is 2. O = O or C = C bond in alkenes. (ii) Bond length: It is the equilibrium distance between nuclei of two bonded atoms in a molecule. (iii) Bond enthalpy: It is the amount of energy required to break one mole of bonds of a particular type between two atoms in a gaseous state. |
