| 31. | The reaction is an electrophilic aromatic substitution, using arsenic acid as the electrophile.
|
| 32. | The reaction is a type of electrophilic aromatic substitution accompanied by elimination of water.
|
| 33. | However, many resonance-stabilized carbocations are insufficiently electrophilic to react with hydrosilanes.
|
| 34. | This is because the thiol groups are nucleophilic while the arsenic atoms are electrophilic.
|
| 35. | There are two main types of polar addition reactions : electrophilic addition and nucleophilic addition.
|
| 36. | These dipoles add to electrophilic alkenes readily.
|
| 37. | They are electrophilic both at the carbonyl carbon but also at the ?-carbon.
|
| 38. | In the Friedel Crafts acylation, acid halides act as electrophiles for electrophilic aromatic substitution.
|
| 39. | The Wheland intermediate is its opposite number and the reactive intermediate in electrophilic aromatic substitution.
|
| 40. | It is more electrophilic than quinone itself.
