Verified step by step guidance1
Understand the definitions: A Lewis acid is defined as a species that can accept an electron pair, while a Brønsted-Lowry acid is defined as a species that can donate a proton (H⁺).
Identify the key distinction: The primary difference between these two types of acids lies in what they interact with. Lewis acids interact with electron pairs, whereas Brønsted-Lowry acids interact with protons.
Analyze the options: Review each option to see which correctly describes the interaction of Lewis acids and Brønsted-Lowry acids with electron pairs and protons.
Option evaluation: A Lewis acid accepts electron pairs, while a Brønsted-Lowry acid donates protons. This matches the definitions provided earlier.
Conclude the correct distinction: The correct distinction is that a Lewis acid accepts electron pairs, while a Brønsted-Lowry acid donates protons, aligning with the fundamental definitions of these acid types.
