Question of the Day

Which of the following is not true for SN₁ reactions?

SN1 reaction is a two-step reaction, step one is the leaving group leaves, and the second step is the substrate forms a carbocation intermediate. Formation of carbocation intermediate is the rate determining step. Since for the formation of stable intermediate carbocation, highly polar solvent is required. The bulky substituents prevent the nucleophiles from approaching the carbon, which is attached directly to the halogen. SN₂ is also more favorable as the neighboring alkyl groups are electron donating, which helps to stabilize the carbocation. SN1 reaction because the nucleophile is not a part of the rate-determining step.

They occur through a single step concerted reaction They are favoured by polar solvents Tertiary alkyl halides generally react through this mechanism In an SN₂ reaction, the rate determining step is the loss of the leaving group to form the intermediate carbocation. Concentration of nucleophile does not affect the rate of such reactions
