Consider the foiiowing SN2 reactions.Q.Only neighbouring effect increases reactivity of (II) by a factor of 5 x 104. If reaction (I) is carried out with initial concentration of C4H9Br = 0.05 M and NaOH 0.01 M and reaction (II) is carried out with initial concentration of both CH3SCH2CH2Br and NaOH = 0.1 M each, rate of reaction (II) would be 10xtimes greater than the rate of reaction (I) under identical experimental condition. What is the value of x? Correct answer is '6'. Can you explain this answer?

PassageThe general mechanism of a SN2 reaction is as follows.Factors that limit the rate of reaction are steric hindrance at α-cabron of substrate and strength of C—X bond. Any factor which stabilises transition state increases the rate of reaction.Q.In the previous question, under identical reaction condition, i.e. tem perature, concentration of substrate and nucleophile, the correct relationship between rate constant is

Passage IIWhen compound 1 is heated with C2H5ONa compound 2 and 3 are formed:Two mechanisms were proposed for reaction I.Mechanism A HBr is eliminated from compound 1 to form a symmetrical vinyl carbene intermediate A, which then rearranges to compound 2.Mechanism B Ethoxide ion first abstract a proton to form a carbanion intermediate B which then rearranges with loss of bromide ion to form compound 2To distinguish between the two machanisms, an isotopic labeling experiment was designed. Two compounds (Compound 4 and 5) were labelled with C-14 and each was treated separately with sodium ethoxide under identical experimental condition where following results were obtained.Q.Compound 2 and 6 can be distinguished from each other by all of the following techniques except
