Question

Which is a characteristic of a Lewis base? it behaves as the electron donor. It behaves as the electron acceptor. It donates a hydrogen ion to other compounds. It increases the concentration of hydrogen ions.

Answer 1

It behaves as the electron donor.

Step-by-step explanation:

Lewis Bases donate an electron pair. Lewis Bases are Nucleophilic meaning that they “attack” a positive charge with their lone pair. They utilize the highest occupied molecular orbital or HOMO (Figure 2). An atom, ion, or molecule with a lone-pair of electrons can thus be a Lewis base.

Answer 2

• It behaves as the electron donar. Its is correct one

Definition of lewis base:

• Lewis base is a such a substance which donate pair of electron to Lewis acid.

Example:

H3N + BF3 ⇒ H3N---≥BF3

• Ammonia is a lewis base while boron trifluride is lewis acid.

Condition

• There should be lone pair of electron
• Negative charged substances or anions
