Question

Which best describes the definition of Lewis acids and bases?

Answer 1

Step-by-step explanation:

According to Lewis, acids are the species that are able to accept an electron pair from a base or electron donating specie.

For example,
`BF_(3)` is a lewis acid as it is able to accept an electron.

On the other hand, a Lewis base is defined as the species that are able to donate an electron pair.

For example,
`NH_(3)` is a lewis base as it can donate a pair of electron to an electron deficient atom.

Answer 2

Step-by-step explanation:

Hello! Let's solve this!

According to Lewis, an acid is a chemical species that has the last orbital space to accept the pair of electrons from Lewis's base.

A Lewis base is a chemical species having the full orbital and has a pair of electrons that are not in the bond and can form a dative bond with a Lewis acid.
