1.	Explain why the following two structures, I and II cannot be the major contributors to the real structure of CH_(3)COOCH_(3). underset((I))(CH_(3) - underset(+)overset(overset(bar( : overset(..)O: ))(\|))(C )- underset(..)overset(..)(O) - CH_(3)) harr underset((II))(CH_(3) - overset(overset(bar( : overset(..)O: ))(\|))(C )= underset(..)overset(+)(O)- CH_(3))
Answer» Solution :In STRUCTURE (I), the octet is not complete on carbon `C^(+)` and the SEPARATION of CHARGE on adjacent atom so it is UNSTABLE and there is no specific ROLE in real structure. The separation of charge is in structure (II) and It is unstable because negative charge (+) on oxygen atom and no specific role.
