Explain the terms Inductive and Electromeric effects. Which electron displacement effect explains the following correct orders of acidity of the carboxylic acids?
(a) `Cl_(3)"CC"OOH gt Cl_(2)CHCOOH gt ClCH_(2)COOH`
(b) `CH_(3)CH_(2)COOHgt(CH_(3))_(2)CHCOOHgt(CH_(3))_(3)C.COOH`

Explanation

### Step-by-Step Solution:

**Step 1: Define Inductive Effect**
The inductive effect is a permanent effect that involves the displacement of sigma electrons in a molecule due to the presence of electron-withdrawing or electron-donating groups. It occurs through the sigma bonds and is classified into two types:
- **Negative Inductive Effect (-I)**: This occurs when an electron-withdrawing group (like -NO2, -Cl, -Br, etc.) pulls electron density away from the rest of the molecule.
- **Positive Inductive Effect (+I)**: This occurs when an electron-donating group (like -CH3, -C2H5, etc.) pushes electron density towards the rest of the molecule.

**Step 2: Define Electromeric Effect**
