Question 5

Which of the following is a correct statement regarding electrophilic aromatic substitution?

Accepted Answer

A)  The carbocation intermediate will lose a proton to regain aromaticity, usually from a position other than the site of electrophilic attack. 
B)  Formation of the carbocation intermediate has a high activation barrier due to loss of aromaticity. 
C)  The carbocation intermediate has several resonance structures and is negatively charged. 
D)  Re-formation of the aromatic ring has a low activation barrier and therefore occurs slowly. 
E)  Many suitable electrophiles are unreactive and can be stored for long periods of time prior to use.
