Question

Which of the following is not true for SN1 reaction ? (A) Favoured by polar solvents (B) 3° - alkyl halides generally react through SN1 reaction (C) The rate of the reaction does not depend upon the molar concentration of the nucleophile (D) 1° - alkyl halides generally react through SN1 reaction.

Tardigrade Admin · Accepted Answer

In S N 1 reactions, rate of the reaction depends upon the concentration of the substrate only. It does not depend upon the concentration of the nucleophile. In this type of reaction, covalent nucleophile reacts/attacks on substrate. 3° alkyl halide generally react by this mechanism, whereas 1° alkyl halide generally follow S N 2 reactions. S N 1 reactions are favoured by polar solvents.

Q. Which of the following is not true for $S_{N} 1$ reaction ?

Favoured by polar solvents

$3^{\circ}$ - alkyl halides generally react through $S_{N} 1$ reaction

The rate of the reaction does not depend upon the molar concentration of the nucleophile

$1^{\circ}$ - alkyl halides generally react through $S_{N} 1$ reaction.
