| S.No. | Inductive effect | Resonance effect |
| 1. | It involves displacement of σ electrons in saturated compounds. | It involves displacement of $\pi$ electrons or lone pair of electrons in unsaturated and conjugated compounds. |
| 2. | Inductive effect can move only upto 3 to 4 carbons. | In this case, movement of electrons all along the length of conjugated system takes place. |
| 3. | In inductive effect, there is slight displacement of $\sigma$ electrons and partial +ve or-ve charge develops. | In this effect, there is complete transfer of $\pi$ electrons and as a result, complete +ve or -ve charge develops. |

Cl2O7(g) + H2O2(aq) → ClO2-(aq) + O2(g) + H+
$\text{CCI}_4(\text{g})\xrightarrow{ \ \ \ \ \ }\text{C}(\text{g})+4\text{CI}(\text{g})$
and calculate bond enthalpy of C – Cl in CCl4(g).$\Delta_\text{vap}\text{H}^\ominus(\text{CCI}_4)=30.5\text{kJ} \ \text{mol}^{-1}.$
$\Delta_\text{f}\text{H}^\ominus(\text{CCI}_4)=-135.5\text{kJ} \ \text{mol}^{-1}.$
$\Delta_\text{a}\text{H}^\ominus(\text{C})=-715.0\text{kJ} \ \text{mol}^{-1},$ where $\Delta_\text{a}\text{H}^\ominus$ is enthalpy of atomisation
$\Delta_\text{a}\text{H}^\ominus(\text{CI}_2)=242\text{kJ} \ \text{mol}^{-1}$
