Which of the followings are Lewis acids? H2O, BF3, H+, and NH4+
Answered Feb 05, 2023
Lewis acids are those acids which can accept a pair of electrons. For example, BF3, H+, and NH4+ are Lewis acids.
conjugates acids = H3O+ & NH4+
Lewis acids are lone pair (of e- ) accepters while Lewis bases are lone pair donators. AlCl3 is a Lewis acid while NH3 is a Lewis base.
(a) Hydroxyl ion is a Lewis base as it can donate an electron lone pair (OH–). (b) Fluoride ion acts as a Lewis base as it can donate any one of...
(a) OH– is a Lewis base since it can donate its lone pair of electrons. (b) F – is a Lewis base since it can donate a pair of electrons. (c) H+...

[Ti(H2O)6]3+ : In this core Ti+3 has one unpaired e- while Sc+3 does not has any unpaired electron.
Ubiquitous resources are available everywhere, while localized resources are available at select locations.
Ans. (3) BCl3 & AlCl3 both have vacant p-orbital & incomplete octet. So they act as Lewis acid.
