Question

What are the limitations of Lewis Concept?

Answer 1

Heya...✋

✨Limitations of Lewis Concept⤵

⏩The important requirement of Lewis Concept is the formation of a coordinate bond when a base reacts with an acid. However, well known acids such as HCl, H2SO4, etc, do not form coordinate bonds.

⏩The neutralisation process is usually fast but the formation of coordinate bond is slow.

⏩Arrhenius and Bronsted concept can explain the strength of acids and bases but Lewis Concept cannot.

⏩The catalytic activity of acids is due to H^+ ions. But many Lewis acids do not possess hydrogen or give H^+ ions.

Hope it helps✅

Answer 2

Answer:

Explanation:

Lewis concept give the general idea and includes all the coordination reactions and coordination compounds this may not be true always

Lewis concept do not explain the behaviour of well known protonic acids like HCL H2 s o4 which do not form coordination bonds with bases therefore according to Lewis these are not regarded as acids

relative strength of acids and bases are not explained by Lewis

many Lewis acids do not possess catalytic property
