Question

2. Order the reactivity of the compounds evaluated in the "Steric Effects" experiment from slowest to fastest? Were these results consistent with the expected results? Discuss why your results were or were not in agreement with the expected results

Steric Effect		Trial One		Trial Two
	Precipitate	Time (seconds)	Precipitate	Time
1-bromobutane	Yes	24.36	Yes	32.47
1-bromo-2-methylpropane	Yes	1.11.34	Yes	1.15.29
1-bromo2,2-dimethylpropane	No		No

Answer 1

The structure of 1 Bromo propane is. The structure of 1-Bromo 2 Methyl Propane is and finally the structure of 1-Bromo 2,2 Dimethyl propane is.

Hence we can expet that the order of reactivity based on steric hindrance is 1-Bromo propane>1-Bromo2 Methyl Propane > 1 Bromo 2,2 Dimethyl propane. The experiment results also in according to theoretical expectation and 1 Bromo propane forms precipitate easily, 1 Bromo 2 Methyl propane forms precipitate within some time and finally 1 Bromo 2,2 Dimethyl propane didnot form precipitate.
