8.A compound has the common name N-methylbenzamide. Which of the following is not true? Question 8 options: N-methylbenzamide must include an aromatic benzene ring N-methylbenzamide contains nitrogen N-methylbenzamide has a carbonyl C=O and nitrogen, therefore is an amide Since N-methylbenzamide has a methyl bonded to nitrogen it must be a secondary amine 9.Which of these types of compounds forms salts with acids?

Please answer all questions.
Chapter 21, Practice problems (Carboxylic Acid Derivatives) 1) Amides are less basic than amines because A) the carbonyl group donates electrons by resonance B) the carbonyl group withdraws electrons by resonance C) the nitrogen does not have a lone pair of electrons D) the nitrogen has a full positive charge E) amides do not contain nitrogen 2) N-Methylacetamide is an example of A) a primary amide B) a secondary amide C) a tertiary amide D) an...

Question 3
1s 3 ORTHO Today we learned about adding a second group to a mono-substituted benzene ring. Any group on a benzene will affect the rate of the reaction (activated or deactivated relative to benzene) and the regioselectivity Where does the electrophile add? Ortho? Meta? Para? Some combination thereof? We found that EDGs (electron-donating groups) direct the electrophile to the ortho and para positions while EWGs (electron-withdrawing groups) direct the electrophile to the meta position. Now, it is time...
