SN1 Reaction: A kinetic Study

Question: Assume that you use 1.00 mL of 2-chloro-2-methylpropane. Calculate the following quantities. Be sure to show your calculations, please. :-)

A. the number of moles of 2-chloro-2-methylpropane used. The density of the liquid is 0.851 g/mL.

B. the number of moles of HCl produced by complete solvolysis of 1.00 mL of 2-chloro-2- methylpropane

C. the volume in milliliters of 0.350 M NaOH required to neutralize the HCl produced by

lab manual).

D. the volume in milliliters of 0.350M NaOH required to neutralize the HCI produced when

solvolysis of 1.00 mL of 2-chloro-2-methylpropane is 50% complete. (This is referred to

as V50% in your lab manual; the volume of base consumed when the reaction is 50%

complete).

Thank You In Advance :-)

Explanation / Answer

A) density =Mass/volume

Mass=densityXvolume =0851X1 =0.851g/ml

no.of moles= 0.851/92.5 =0.0092 (molecular weight of t-butyl chloride is 92.5g)

B)as per the reaction it is 1:!, so nof moles of HCl is 0.0092moles

C) molarity of Hcl is 0.092/1X1000=9.2M

M1V1=M2V2

9.2X1= 0.350XV2

V2=26.28ml

So, 26.28ml of NaOH equired.

D) volume required for 50% of reaction is V50%=26.28/2= 13.14ml
