Which of the following statements is not true?
A)Sodium ethoxide is a better nucleophile than sodium tert-butoxide.
B)Sodium tert-butoxide and sodium ethoxide have similar strengths as bases.
C)Sterically hindered bases are also called nonnucleophilic bases.
D)Steric hindrance decreases basicity but not nucleophilicity.

Question

Quizplus · Accepted Answer

Steric hindrance decreases basicity because it makes it more difficult for the base to accept a proton. However, steric hindrance does not necessarily decrease nucleophilicity, as a bulky nucleophile like tert-butoxide can still attack a less hindered electrophile. Therefore, statement D is not true.
