Acids and Bases - What are the Relationships between Acidity and Molecular Structure?

5 important questions on Acids and Bases - What are the Relationships between Acidity and Molecular Structure?

How does electronegativity influence the acidity?

The more electronegative a compound is the higher the acidic strength.

How does resonance influence the acidity?

When the conjugated base of an acid has resonance stabilization the acidity will be higher.

What is the inductive effect?

The inductive effect is the delocalization of electron density trough covalent bonds by a nearby atom of higher electronegativity.

How does the inductive effect influence the acidity?

The larger the inductive effect the stronger the acidity.

How does the size and delocalization of charge in A- influence the acidity?

The more stable A- the stronger the acidity. Hydrogen halides become more stable when they are bigger. So do A- ions. This is because the charge is more delocalized.
