Question

Question 34 Draw the major and minor product(s) that are expected for the following reaction. If only one product is formed, draw it as the major product, and select no reaction for the minor product. Draw all of the minor products if more than one will form in the following reaction. Br Get help answering Molecular Drawing questions. x Your answer is incorrect. Try again. Draw the major product: Edit CH, Get help answering Molecular Drawing questions. Your answer is partially correct. Try again. Draw the minor product(s):

Answer 1

The complete reaction with the step wise arrow pushing mechanism is given as below:-

This is known as an elimination reaction in the presence of the strong base like NaOH. Here, 2 degree carbocation formation takes place which is less stable carbocation intermediate. Further, E2 elimination reaction takes place and more stable substituted alkene is due to more more hyperconjugation. Further, less substituted alkene and SN2 reaction will give the minor product. Dots represent the lone pair of electrons. So, the complete reaction with the step wise arrow pushing mechanism is given as below:-
