Assertionj: The following structures (I) and (II) canot e the major contributors to the real structure of CH_(3)COOCH_(3) CH_(3)-underset(I)underset(+)overset( : overset(..)(C)^(-): )overset(|)(C)-underset(..)overset(..)(O)harrunderset(II)(CH_(3)-overset( : overset(..)(O)^(-): )overset(|)(C)=underset(..)overset(+)(O)-CH_(3)) Reason: Both the structures involve charge separation and structure (I) contains a carbon atom with an incomplete octet.
