Question
Identify the Laws acid and Lewis base from among the reactants in each of the following equations Cr^3+(aq) + 6H_2O(l) Cr(H_2O)^3+_6 (aq) Cr^3+ is the Laws acid and h_2 0 is the Lewis base H_20 is the Lewis acid and Cr^3+ is the Lewis base NH_3 is the Lewis acid and Cu^2+ s the Lewis base C_u^2+ is the Lewis acid and NH_3 is the Laws base (C_2H_5)_2 O(g) + BF_3(g) (c_2H_5)_2 OBF_3(g) BF_3 is the Laws acid and (C_2H_5)_2 O is the Lewis base (C_2H_5)_2 0 is the laws acid and BF_3 is the Lewis baseExplanation / Answer
H2O is the Lewis acid and Cr3+is the Lewis base
Water is a weak base. The hexa-aqua complex will therefore behave as a weak acid and will partially dissociate
Cu2+ is the Lewis acid and NH3 is Lewis base
A Lewis base species can bond by donating a lone pair of electrons. Here NH3 donate the electron pair
BF3 is the Lewis acid and (C2H5)2O is the Lewis acid base
BF3 is strong Lewis acid. A Lewis acid a species can form bond by accepting a lone pair of electrons.
