D Question 11 6 pts Which structure is a major organic product of the multi-step reaction shown? Recall that the numbers in front of the reagents tells the order of the addition 1) NaNHANH, 2) CH CH Br 3) HgSO4/H2SO4/H,0 // D Question 14 6 pts Which group is considered a deactivator in electrophilic aromatic substitution (EA.S.) reactions? The dashed line indicates where the group is attached to benzene. OH —ОН
D Question 1 5 pts Grignard reagents can be used to convert esters into tertiary alcohols after an acid workup. True False Question 2 7 pts The sigma complex intermediate formed during electrophilic aromatic substitution (EAS) reactions is resonance stabilized. Electron donating groups (EDGs) typically make the intermediate more stable and electron withdrawing groups (EWGS) typically make the intermediate less stable. Using this information, which statement is correct regarding EDGs versus EWGS? The stability of the sigma complex has nothing...
MULTIPLE ANSWER CHOICES ARE POSSIBLE (more than one correct) Question 7 Which of the following statements are true about the deactivating nitroso substituent in electrophilic aromatic substitution reactions? NFO The nitroso group is predicted to be an ortho/para-directing group. Resonance withdrawing effects can explain why the nitroso group is deactivating. The nitroso group is predicted to be an meta-directing group. Inductive withdrawing effects can explain why the nitroso group is deactivating.
