Answer:

  • 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

Answer:

It behaves as the electron donor.

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.
