Chemistry Question on Chemical Reactions of Haloalkanes and Haloarenes
If all the nucleophilic substitution reactions at saturated carbon atoms in the above sequence of reactions follow Sn2 mechanism, then E and F will be respectively,
A
B
C
D
Answer
Explanation
Solution
The correct answer is option (D):
In this category of haloalkane chemical reactions, the nucleophile will go after an electron-deficient site and replace the halogen or X there.
The electronegative halogen component will pull electrons away from the bond in the case of alkyl halides and attract them towards it, polarising the bond. As a result, the carbon atom will acquire a partial positive charge, becoming an electron-deficient site.
