Solution
The correct option is D Carbenes are highly unstable
In α− Elimination reaction, the leaving group and the proton are removed from the same α− carbon which leads to formation of reactive carbene intermediate. Thus, statement (iii) is correct.
Since both leaving group and proton removes from single carbon it is also know as 1, 1-Elimination reaction.
Intermediate of E1 elimination reaction is carbocation.
Carbene intermediate is very reactive in nature because its electron valency is 6. Due to its electron valence, it is electron deficient and more reactive intermediate. Thus, it is highly unstable.
Thus, statement (iv) is correct.
