| 21. | They undergo nucleophilic addition and substitution reactions with various electrophiles.
|
| 22. | Enol ethers and glycals are nucleophilic enough to be fluorinated by Selectfluor.
|
| 23. | I don't think nucleophilic or Lewis acid catalysis is involved.
|
| 24. | Organohalogens are also synthesized through the nucleophilic abstraction reaction.
|
| 25. | In many nucleophilic reactions, addition to the carbonyl group is very important.
|
| 26. | Ordinary alkenes are not susceptible to a nucleophilic attack ( apolar bond ).
|
| 27. | Two mechanisms have been proposed : a radical mechanism and a nucleophilic mechanism.
|
| 28. | Several models exist to describe chiral induction at carbonyl carbons during nucleophilic additions.
|
| 29. | The nucleophilic attack is the rate-determining step.
|
| 30. | LDA is a strong, non-nucleophilic base.
