(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.
