Question

Statement 1: RI is more reactive than RCl towards $S_{N}$ reaction.
Statement 2:The rate of reaction for $S_{N}1$ or $S_{N}2$ mechanism is $RI > RC1.$

• A. If both Statement 1 and Statement 2 are true and the statement 2 is the correct explanation o f the statement 1.
• B. If both Statement 1 and Statement 2 are true but statement 2 is not the correct explanation of the statement 1.
• C. If Statement 1 is true but Statement 2 is false.
• D. If Statement 1 is false but Statement 2 is true.

Answer 1

Answer: (A)

The rate of reaction for alkyl halide is $RI > RBr > RC1 > RF$ whether it obeys $S_{N^1}$ or $S_{N^2}$ mechanism due to steric hindrance of alkyl group.
