Please need an answer on why was tert butyl chloride washed with aqueous sodium hydrogen carbonate? What gas was evolved during the washing and write a balanced equation .

Why was tert butyl chloride washed with aqueous sodium hydrogen carbonated?

Need answers

1. Why was the tert. Butyl chloride washed with aqueous sodium hydrogen carbonate? What

gas was evolved during the washing? Write a balance equation
2. Why was the tert.butyl chloride finally washed with water?
3. Write a balanced equation for the overall preparation. Since tert butanol was the limiting
reagent, calculate the theoretical yield (and % yield) of the tert.butyl chloride.
4. Given the following alcohol (i) 3-pentanol (ii) 2-pentanol (iii) 1-pentanol
(iv) 2-methyl-2-butanol:
(a) Draw the structures of the given alcohols and classify each as primary, secondary or
tertiary.
(b) Which of the given alcohols will react most rapidly with hydrogen bromide (HBr) and
which will react least rapidly? Write/draw the structure of the product in each case.
5. It is known that secondary and tertiary alcohols sometimes undergo rearrangement when
treated with hydrogen halides (HX) whilst primary alcohols do not. Mechanistically,
secondary and tertiary alcohols undergo reaction with HX by SN1 pathway while primary
alcohols by SN2 pathway.
With respect to the mechanism given, describe the importan

To neutralise the excess HCL.
