MEDIUMMCQ SINGLENEET ChemistryInorganic ChemistryAlkyl and Aryl HalidesE elimination follows an antiperiplanar structure
(a) (b) (c) (d)
Answer
A
Explanation
Since the leaving group is highly withdrawing but strongly bonded, the eliminations is 1 E -CB . Thus, the alkene obtained is least substituted, i.e. ethene from the ethyl group attached to N. 81. What is the major product of the reaction sequence? (a) (b) (c) (d) Addition of 3 C H I (excess) methylates the amino group. Next addition of 2 Ag O , 2 H O/Δ represents 1 E -cb mechanism, giving Hoffman product. In the first step the amine group will be replaced with iodine and in the second step there is the formation of alkene. The reaction is given below:
