The leaving group is that functional group which is ejected with electrons of the o-bond in a reaction. Better the leaving group, faster is the reaction. The relative leaving abilitiy of the leaving group X in (R-X) is increased by:
i. The polarisability of (R-X) bond ii. The degree of stabilisation through solvation of X.
iii. The strength of (R-X) bond. iv. The stability of `X^(Theta)`.
The leaving group tendency is also called fugacity.
Which statement is wrong?

Options

A. In polar aprotic solvents such as DMSO, DMF, and DMA, the fugacity order is `I^(Theta)gt Br^Theta gt Cl^Theta gt F^Theta`
B. Strong bases are good leaving groups.
C. The leaving group order of the following is: `OH^(Theta) gt RO^(Theta) gt CH -= C^(Theta) gt ""^ThetaNH_2`
D. Charged species are good leaving group than neutral species.

Answer

B

Explanation

Weak bases are good leaving groups.
