Question

Show how compound act as lewis acid and lewis base

Answer 1

$ASSALAMUALAIKUM$


A Lewis acid-base reaction occurs when a base donates a pair of electrons to an acid. A Lewis acid-base adduct, a compound that contains a coordinate covalent bond between the Lewis acid and the Lewis base, is formed. The following equations illustrate the general application of the Lewis concept.

The boron atom in boron trifluoride, BF3, has only six electrons in its valence shell. Being short of the preferred octet, BF3 is a very good Lewis acid and reacts with many Lewis bases; a fluoride ion is the Lewis base in this reaction, donating one of its lone pairs:

Answer 2

Lewis acid = electron acceptor
Lewis base = electron donor
Water, H2O, is the most common and well-known compound that can act as both a Lewis acid and a Lewis base.
