Given below are the two types of mechanism of the reaction:
(a)[1.0]
Why is the product obtained in (A) pathway optically inactive?
(b)[1.0]
Investigate the effect of plane polarised light on the product of (B) pathway? Which pathway shows faster reaction?
Answer
Answer (a)
Official answer key
Pathway A follows $S_N1$ mechanism in which attack of nucleophile on carbocation takes place from front and back side, gives racemic mixture which is optically inactive.
Answer (b)
Official answer key
The product obtained in pathway B rotates the plane polarised light in opposite direction than that of substrate. Pathway A is faster than pathway B.
