ANSWER:Problem 16.121In many reactions the addition of AlCl produces the same effect as the addition of H . (a) Draw + 3a Lewis structure for AlCl in which no atoms carry formal charges, and determine its structure 3using the VSEPR method. (b) What characteristic is notable about the structure in part (a) thathelps us understand the acidic character of AlCl (c) Predict3he result of the reaction betweenAlCl 3d NH in a3olvent that does not participate as a reactant. (d) Which acid base theory is +most suitable for discussing the similarities between AlCl and H 3 Step-by-step solution Step 1 of 4 (A) Lewis structure of AlCl :- 3 Al has 3 valence electrons and Cl has 7 valence electrons. Total number of valence electron - = 3 + 3(7) = 24e Al has 3 bonding domain with three equivalent Al-Cl bond. Thus according to VSEPR method, it has trigonal planar geometry.
