(a)
Interpretation:
The major and minor product must be predicted for the given E2 reaction.
Concept Introduction :
Unless the bulky base is used generally more substituted
(b)
Interpretation:
The major and minor products must be predicted for the given E2 reaction.
Concept Introduction :
In E2 reaction if bulky base is used, then hydrogen abstraction takes place from less hindered carbon.
(c)
Interpretation:
The major and minor products must be predicted for the given E2 reaction.
Concept Introduction :
Tertiary alkyl iodide undergoes E2 reaction to produce more substituted alkene as the major product.
(d)
Interpretation:
The major and minor products must be predicted for the given E2 reaction.
Concept Introduction :
The bulky base in E2 reaction produces less substituted alkene as the major product.
(e)
Interpretation:
The major and minor products must be identified for the given E2 reaction.
Concept Introduction :
The less bulky bases prefer to take hydrogen from more hindered carbon in order to produce most substituted alkene as the major product.
(f)
Interpretation:
The major and minor products must be identified for the given E2 reaction.
Concept Introduction :
The bulky bases prefer to take hydrogen from less hindered carbon in order to produce less substituted alkene as the major product.

Use the Zaitsev rule to determine the major product.arrow_forwardAll rearrangements we have discussed so far have involved generation of an electron-deficient carbon followed by a 1,2-shift of an atom or a group of atoms from an adjacent atom to the electron-deficient carbon. Rearrangements by a 1,2-shift can also occur following the generation of an electron-deficient oxygen. Propose a mechanism for the acid-catalyzed rearrangement of cumene hydroperoxide to phenol and acetone.arrow_forward
