Statement I: (S)-2-Bromobutane on treatment with SH− at 50°C in DMSO gives inverted product
Statement II: This reaction follows SN2 pathway
Answer & explanation
Correct answer: option 1
The correct answer is option 1. Both statement I and statement II are correct and statement II is the correct explanation of statement I.
Statement I: (S)-2-Bromobutane on treatment with SH− at 50°C in DMSO gives inverted product
Statement I is correct because (S)-2-bromobutane is an optically active compound, and the SN2 reaction with SH− at 50°C in DMSO is a concerted reaction that proceeds with inversion of configuration. This means that the product of the reaction will be the (R)-2-butanthiol.
Statement II: This reaction follows SN2 pathway
Statement II is also correct because the SN2 reaction is a nucleophilic substitution reaction that proceeds with the attack of a nucleophile on the back side of the electrophile. This attack results in the inversion of the configuration of the reactant.
Therefore, both statements I and II are correct, and statement II is the correct explanation of statement I.
