diff b/w lewis acid and base

Postby Mallika Singh 1G » Sun Nov 03, 2019 7:06 pm

What classifies a molecule as a Lewis acid or base? Is it just dependent on who receives the e pair in the reaction?

A Lewis acid accepts an electron pair, and a Lewis base donates a pair of electrons!

A Lewis base is defined as a species that donates an electron pair (has lone pair electrons) while a Lewis acid is defined as a species that accepts an electron pair (has vacant orbitals). The acceptance of an electron pair by the Lewis acid from the Lewis base enables the formation of a coordinate covalent bond. Hope this helps!

Acids accept while the bases donate electron pairs!

Also acids are usually positively charged and bases are more likely negatively charged

Acids are also usually transition metals such as Cobalt which have a positive ionization charge, allowing it to accept lone pairs from other elements.

Lewis acids accept electrons while bases donate electrons. Acids are more positive and bases are more negative.

Is (HPO4)2- a base because it has a negative charge?

Lewis acids: accept an electron pair
Lewis bases: donate a pair of electrons

Also, generally speaking, anions will act as Lewis bases (donate an electron pair) while cations act as Lewis acids (accept an electron pair)

A lewis acid is and electron acceptor and a lewis base is an electron donor

A Lewis base is an electron donor, while a lewis acid is a proton donor

Lewis acids are electron - pair acceptors and Lewis bases are electron - pair donors.
