The bond strength increases:

Mr. S M HUSSAIN · Accepted Answer

## CORE INFORMATION
✓ **Answer**: D
## CONCEPT FRAMEWORK
	**Primary Concept**: Factors affecting bond strength
	**Related Topics**: Molecular orbital theory, Covalent bonding
	**Prerequisites**: Understanding of chemical bonds and atomic orbitals
## SOLUTION PATHWAY
**Given Information**:
	The question asks about factors that increase bond strength.
**Method & Steps**:
	1. Analyze each option individually in terms of its effect on bond strength:
		Reasoning: Bond strength is directly related to the number of bonds and the effectiveness of orbital overlap.
	2. Evaluate option A:
		Working: Increasing bond order (single, double, triple bond) increases the number of shared electrons, leading to a stronger bond.
		Key Point: Higher bond order implies more electron density between the nuclei.
	3. Evaluate option B:
		Working: Greater overlap between orbitals leads to a greater electron density between the nuclei, resulting in a stronger bond.
		Key Point: Effective overlap maximizes attractive interactions.
	4. Evaluate option C:
		Working: When the energies of overlapping orbitals are closer, the orbitals interact more effectively, leading to stronger bonding.
		Key Point: Similar energies promote effective mixing and bonding.
	5. Conclude:
		Result: All three options independently lead to an increase in bond strength. Therefore, the correct answer is D.
## OPTION ANALYSIS
[A] :x: Incorrect because it is not the only correct option.
[B] :x: Incorrect because it is not the only correct option.
[C] :x: Incorrect because it is not the only correct option.
[D] ✓: Correct because all of the given factors lead to an increase in bond strength.
## LEARNING AIDS
	**Common Mistakes**:
		1. [Error 1]: Focusing on only one factor and ignoring the others.
		   [How to avoid]: Consider all factors that contribute to bond strength.
		2. [Error 2]: Incorrectly associating energy difference with bond strength.
		   [How to avoid]: Remember that closer orbital energies result in stronger interactions.
	**Quick Tips**:
		1. [Helpful shortcut]: Use the mnemonic 'BOE' (Bond Order, Overlap, Energy difference) to remember the factors that influence bond strength.
		2. [Memory aid]: Visualize the overlapping orbitals as contributing to the electron density between the nuclei; the more overlap, the stronger the bond.
