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

To answer the question, we will first explain the terms "Inductive Effect" and "Electromeric Effect," and then we will analyze the given orders of acidity of the carboxylic acids to determine which electron displacement effect explains them.

### 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.

- **Types of Inductive Effect:**
- **+I Effect (Positive Inductive Effect):** This occurs when electron-donating groups (such as alkyl groups) are present, which push electrons away from themselves.
- **-I Effect (Negative Inductive Effect):** This occurs when electron-withdrawing groups (such as halogens) are present, which pull electrons towards themselves.
