Given three points of differences between inductive effect and resonance effect.

Explanation

### Step-by-Step Solution:

**1. Definition of Inductive Effect and Resonance Effect:**
- **Inductive Effect:** It refers to the permanent polarization of a bond due to the electronegativity difference between atoms, resulting in the shifting of sigma electrons.
- **Resonance Effect:** It involves the delocalization of pi electrons across adjacent atoms, leading to the stabilization of a molecule through resonance structures.

**2. First Point of Difference: Type of Electrons Involved**
- **Inductive Effect:** Involves the delocalization of only sigma electrons. This effect occurs in saturated compounds where there are no pi bonds.
