Due to electron delocalization, one would predict that the carbon-oxygen bond in acetamide, CH3CONH2, .A) is nonpolarB) has more double bond character than the carbon-oxygen bond of acetone, (CH3)2COC) is longer than the carbon-oxygen bond of dimethyl ether, (CH3)2OD) is longer than the carbon-oxygen bond of acetone, (CH3)2COE) is formed by overlapping sp3 orbitals

D) is longer than the carbon-oxygen bond of acetone, (CH3)2CO

Explanation:

Delocalization has to to do with a situation in which electrons are not associated with with a single covalent bond in a molecule.

If a double bond is involved in delocalization, then it tends to exhibit greater single bond character. This implies that the bond will be longer than a normal double bond.

If we bring these ideas home to our particular context of CH3CONH2 and acetone, delocalization confers greater single bond character on CH3CONH2 making its C=O bond longer than that of acetone where there is no delocalization.

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.
