In Section 15.5c, we learned that the frequency of the C=0 stretch for an amide is lower than it is for a ketone, suggesting that the C=0 bond is weaker in an amide. This weakening of the C=0 bond can be explained by the significant contribution from one of its resonance structures toward the resonance hybrid. Draw that resonance structure for N,N-dimethylacetamide [CH3CON(CH3)2] and explain how it accounts for the weakening of the C=0 bond.

A chemist synthesized compound X as a racemic mixture. When the ketone group in X was enzymatically reduced to the corresponding alcohol, a 100% yield was obtained of the product shown below. Choose the statement that best describes this result. ОН enzyme C;H1 `OCH,CH; pH 4.0 C3H1 `OCH,CH3 ОН ÕH X (racemic) (100% yield) One enantiomer of compound X reacts quickly with the enzyme. The other enantiomer of compound X is unreactive, but rapidly equilibrates with the reactive enantiomer under the reaction conditions. Since compound X was racemic, it makes sense that only a single product was obtained. O The product is a meso compound, so either enantiomer of compound X gives the same product. One enantiomer of compound X reacts quickly with the enzyme, while the other enantiomer of compound X remains unchanged.

Nitration of an aromatic ring involves an electrophilic substitution reaction. Draw the structure of the electrophile that is attacked by the aromatic ring and the intermediate formed after attachment of the electrophile to the ring. Be sure to show formal charges.
What is false about "Amide plane"? O Mother Nature requires the bond "C=N" to be "trans", putting two a-carbons to two sides of the C=N bond. All four atoms in the bond (-CO-NH-), the two alpha carbons that they connect, also the R-groups, all lie in the same plane. There is a resonance form of the bond (-CO-NH-) that causes a "C=N* double bond to form. The "C=N" bond is flat or "planar" and does not rotate.
