Question

________occurs when no single Lewis structure adequately represents the bonding in an organic molecule.

The _________ results in the partial redistribution of electron density in a molecule through bonds, driven by differences in electronegativity.

The presence of electron withdrawing groups tends to increase the strength of an acid

Delocalizing electron density of the conjugate base through resonance results in a decrease in the acidity of the molecule.

True or False

True or False

Delocalizing electron density of the conjugate base through resonance results in a decrease in the acidity of the molecule.

True or False

Explanation / Answer

Fill in the blanks:-

A) resonance occurs when no single lewis structure adequately represent bonding in an organic molecule.

B) The inductive effect results in partial redistribution of electron density...................

True/false

A) true

Acidic strength is directly proportional to conjugate base stability.electron withdrawing group stablise conjugate base and hence increase acidic strength.

B) false

Delocalisation leads to stability and hence increase acidic strength.
