The major product B formed in the following reaction sequence, and overall yield of its formation are 
A 
B
A B(a)
and 48 %
and 48 %(b)
and 70 %
and 70 %(c)
and 48 %
and 48 %(d)
and 70 %
and 70 %Answer
Answer (as printed): A
Explanation
60 80 % yield = × ×100 = 48% 100 100 Therefore option (b) and (d) are not possible Since the reaction did not happen at the stereocentre, thus stereochemistry of the reactant will be preserved in the product.
