Which of the following statements is true?
A)All good leaving groups are strong bases with weak conjugate acids.
B)Left-to-right across a row of the periodic table,leaving group ability decreases.
C)Down a column of the periodic table,leaving group ability decreases.
D)The conjugate bases of strong acids are good leaving groups.

Question

Quizplus · Accepted Answer

The conjugate bases of strong acids are good leaving groups because they are stable and can accept electrons easily. Strong acids have weak conjugate bases, which means they are stable and can easily leave the molecule in a reaction. Therefore, option D is correct. Option A is incorrect because not all good leaving groups are strong bases with weak conjugate acids. Option B and C are incorrect because leaving group ability increases down a column and from right to left across a row of the periodic table.
