Vedclass · Answer

(C) Let's analyze each reaction based on the criteria:$(1)$ $HBr, ROOR$ (Free radical addition): Stereochemistry is non-stereospecific (mixture of $syn$ and $anti$). Regiochemistry is $anti-Markovnikov$.$(2)$ $Br_2 - H_2O$ (Halohydrin formation): Stereochemistry is $anti$ addition due to the formation of a cyclic bromonium ion intermediate. Regiochemistry is $Markovnikov-like$ ($OH$ attacks the more substituted carbon).$(3)$ Hydroboration-oxidation: Stereochemistry is $syn$ addition (the $H$ and $OH$ add to the same face of the double bond). Regiochemistry is $anti-Markovnikov$ ($OH$ adds to the less substituted carbon).$(4)$ $HBr$ (Electrophilic addition): Stereochemistry is non-stereospecific (mixture of $syn$ and $anti$ due to carbocation intermediate). Regiochemistry is $Markovnikov$.Comparing with the criteria:$(A)$ $SYN$ $ONLY$: Only reaction $(3)$ satisfies this.$(B)$ $Anti-Markovnikov$: Only reaction $(1)$ and $(3)$ satisfy this.Therefore,reaction $(3)$ fits both criteria.

Some addition reactions of alkene are given below. Identify the one which fits on $ALL$ the given criteria.
Reaction must have-
$(A)$ Stereochemistry of addition - $SYN$ $ONLY$
$(B)$ Regiochemistry of addition - $ANTI-MARKOVNIKOV$ $OR$ $ANTI-MARKOVNIKOV$ $LIKE$
