Question

Which of the following statements are correct for the given reaction:
$R-OH\stackrel{X^{\theta }}{\to }R-X+\stackrel{\theta }{O}H$

• A. Reaction will not take place because is poor leaving group; $X^{\theta }$ is weak base.
• B. Reaction will not take place because $O{H}^{-}$is poor leaving group and
  $X^{\theta }$ is strong base.
• C. Reaction will take place because $O{H}^{-}$is poor leaving group and ​ $X^{\theta }$ is weak base whereas is
  strong base.
• D. Reaction will take place because $O{H}^{-}$ is good leaving group,​ $X^{\theta }$ is weak base and is strong base.

Answer 1

The correct option is A Reaction will not take place because is poor leaving group; $X^{\theta }$ is weak base.

a) Reaction will not take place because is poor leaving group; $X$is weak base. Conjugate base of a weak acid is strong and vice-versa.
