Which of the following statements is NOT supported by the results in Tables 1 and 2?A.In Experiment 2, crotyl chloride forms a stable carbocation.B.Primary alkyl halides react more readily in SN2 reactions than in SN1 reactions.C.Nucleophilic substitution reactions are not dependent on the substrate (alkyl halide) substitution.D.Bromide is a better leaving group than chloride and enhances reactivity in less favorable reactions.

Statement - I: High concentration of strong nucleophilic reagent with secondary alkyl halides which do not have bulky substituents will follow SN2SN2 mechanism.Statement - II: A secondary alkyl halide when treated with a large excess of ethanol follows SN1SN1 mechanism.In the the light of the above statements, choose the most appropriate from the questions given below:JEE Main 2024 (30 Jan Shift 2)AStatement I is true but Statement II is false.BStatement I is false but Statement II is true.CBoth statement I and Statement II are false.DBoth statement I and Statement II are true.

Which of the following is true regarding the relative stability of carbocation and carbanion species as the number of alkyl substituents increases relative to hydride substituents?A.As the number of alkyl substituents increases, carbocation stability increases but carbanion stability decreases.B.As the number of alkyl substituents increases, carbocation stability decreases but carbanion stability increases.C.As the number of alkyl substituents increases, carbocation stability and carbanion stability both increase.D.As the number of alkyl substituents increases, carbocation stability and carbanion stability both decrease.

(i) CH2 - Br + KOH - CH3OH + KBr Write types of nucelophillic substitution reaction in the above reaction (i) and (ii)?(b) Write two differences between mechanism of reaction (i) and (ii)?

Which of the following statements is true?Select answer from the options belowThe rates of SN1 and SN2 reactions are not dependent on the concentration of the nucleophile.Only the rate of an SN1 reaction (not the rate of SN2 reaction) is dependent on the concentration of the nucleophile.Only the rate of an SN2 reaction (not the rate of SN1 reaction) is dependent on the concentration of the nucleophile.The rates of SN1 and SN2 reactions are highly dependent on the concentration of the nucleophile.
