diff b/w lewis acid and base

[Mallika Singh 1G]

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

[sbeall_1C]

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

[TheresaDsilva4A]

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!

[Maia_Jackson_2C]

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

[Chetas Holagunda 3H]

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.

[Jorge Ramirez_4H]

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

[Eunice Nguyen 4I]

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

[Sanjana K - 2F]

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

[BritneyP- 2c]

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

[105289321]

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

[Presley Gao 2C]

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