I know that a Lewis acid is an electron-pair acceptor, and a Lewis base is an electron-pair donor. So in this case: CH
3NH
2(g)+HBr(g)
CH
3NH
4Br(s), HBr is the Lewis acid and the other one is the base, right? But do they have to form a covalent bond at the end?
In this reaction: Al(NO
3)
3(s)+6H
2O(l)
Al(H2O)
63+(aq)+NO3
-(aq), can the reactants still be classified as Lewis acid and base?
I am just not sure if the electron pair donor and the electron pair acceptor have to form a covalent bond.
Thanks!!
