Show the product(s) expected from the reaction of the Grignard reagent formed from ethyl bromide with 2-pentanone. Does the reaction generate a chiral center? Is the product/product mixture chiral or achiral?
Why do we use an ammonium chloride solution rather than only water in the work-up of the Grignard reaction? (Hint: look at the reaction shown below.
Alcohols (ROH) have a pKa of about 16 and water has a pKa of 15.7. Ammonium ion is more acidic than these with a pKa of 9.24.)
