Question

identify lewis acids and bases

Answer 1

where are options LOL :)

Answer 2

those compound which can accept a pair of electrons are lewis acids,they may be ionic or neutral or a compound,like BF3,AlCl3,H+,they may have incomplete octet or vacant d orbitals..

but in case of lewis bases,they donate a pair of electrons,like NH3,Cl- etc.

Answer 3

A Lewis acid is therefore any substance, such as the H+ ion, that can accept a pair of nonbonding electrons. In other words, a Lewis acid is an electron-pair acceptor.
A Lewis base is any substance, such as the OH- ion, that can donate a pair of nonbonding electrons. A Lewis base is therefore an electron-pair donor.
