Which of the choices explains why one nucleophile is stronger than another nucleophile? More than one answer is possible. It is also possible that NONE of these is correct. 7 A stronger nucleophile is larger than another nucleophile. A stronger nucleophile has a less electronegative nucleophilic atom than another nucleophile. A stronger nucleophile has less steric hindrance than another nucleophile. Using this information, in methanol, CH3OH, which of the following is a stronger nucleophile, trimethylamine, (CH3)3N, or dimethylether, (CH3)20? SS...

Question 7 Which of the following statements are true about the deactivating nitroso substituent in electrophilic aromatic substitution reactions? NFO The nitroso group is predicted to be an ortho/para-directing group. Resonance withdrawing effects can explain why the nitroso group is deactivating. The nitroso group is predicted to be an meta-directing group. Inductive withdrawing effects can explain why the nitroso group is deactivating.
