Answer the following questions on this sheet using words, chemical structures and reaction
equations as required.
1)
Using chemical structures draw the complete chemical reaction mechanism of the
reaction of 2 methyl 2 butanol with HCl, provide all the products and any intermediates
involved
(1.0 point)
2)
For reaction drawn above, what is the
theoretical yield
if you started with 1.5 mL of 2
methyl 2 butanol (MW = 88.15 g/mol; density = 0.805 g/mL) and
excess
HCl to produce the
product (MW= 106.59.15 g/mol)? .
1.0 point
Theoretical yield = (1.5/0.805) x 106.59 = 198.61 g
