The facts that can be suggested about the mechanism of the reaction for the given result are to be predicted. Concept introduction: Electrophiles are electron-deficient species, which has positive or partially positive charge. Lewis acids are electrophiles that accept electron pair. Nucleophiles are electron-rich species, which has negative or partially negative charge. Lewis bases are nucleophiles that donate electron pair. Nucleophilic substitution reaction is a reaction in which an electron-rich nucleophile attacks the positive or partial positive charge of an atom or a group of atoms to replace a leaving group. Aryl halides undergo nucleophilic substitution reaction in the presence of a strong nucleophile. Nucleophilic substitution reactions of aryl halides proceed through the elimination addition mechanism and benzyne is formed as the intermediate. Hydroxide ions are nucleophiles; they are negatively charged species.

3. Titanium(III) chloride can be used to catalyze the polymerization of ethylene. It is prepared by hydrogen reduction of Titanium(IV) chloride. Reaction of hydrogen gas with titanium(IV) chloride gas produces solid titanium(III) chloride and hydrogen chloride gas. (a) Write a BALANCED chemical reaction for the preparation of titanium(III) chloride (b) A 250 L reaction vessel at 325°C is filled with hydrogen gas to a pressure of 1.3 atm.
