Understanding Lewis Acids and Bases

What is the primary characteristic of a Lewis acid?

• It donates a proton.

• It accepts a lone pair of electrons.

• It accepts a proton.

• It donates a lone pair of electrons.

Who is credited with the concept of Lewis acids and bases?

• Arrhenius

• Lavoisier

• Brønsted

• Gilbert Lewis

How do Lewis bases differ from Brønsted-Lowry bases?

• Lewis bases accept protons.

• Lewis bases accept electron pairs.

• Lewis bases donate electron pairs.

• Lewis bases donate protons.

In the context of Lewis theory, what does OH- act as?

• A Brønsted-Lowry acid

• A Lewis base

• A neutral compound

• A Lewis acid

What is a key difference between Lewis and Brønsted-Lowry definitions?

• Lewis focuses on protons, Brønsted-Lowry on electrons.

• Both focus on electrons.

• Both focus on protons.

• Lewis focuses on electrons, Brønsted-Lowry on protons.

In a reaction between oxide ions and sulfur trioxide, which acts as the Lewis acid?

• Oxide ions

• Sulfur trioxide

• Water

• Sulfate ions

What role does sulfur trioxide play in the reaction with oxide ions?

• It acts as a solvent.

• It donates electron pairs.

• It accepts electron pairs.

• It donates protons.

Which of the following is a Lewis base in the reaction between oxide ions and sulfur trioxide?

• Sulfur trioxide

• Sulfate ions

• Oxide ions

• Water

What is the significance of Lewis dot structures in identifying Lewis acids and bases?

• They show the number of protons.

• They illustrate electron pair distribution.

• They indicate molecular weight.

• They display atomic numbers.

Why are Lewis acids and bases considered opposites in terms of charge?

• Lewis acids are positively charged, bases are neutral.

• Lewis acids are negatively charged, bases are neutral.

• Lewis acids donate positively charged protons, bases accept them.

• Lewis acids accept negatively charged electrons, bases donate them.
