The first reaction is a Friedel-Craft acylation (or C-acylation) of benzene. The second and third reactions involve phenol. Explain why the second reaction (C-acylation) is a very poor reaction, even in the presence of AICI), and why the third reaction (0-acylation) is preferred. Friedel-Craft acylation (or C-acylation) Extremely poor yield. 5. w.. - - Decent yield (0-acylation) Write the mechanism for a Frieldel-Craft acylation of benzene with acetaldehyde in the presence...

4. The first reaction is a Friedel-Craft acylation (or C-acylation) of benzene. The second and third reactions involve phenol. Explain why the second reaction (C-acylation) is a very poor reaction, even in the presence of AlCl3, and why the third reaction (0-acylation) is preferred. H3C0 + HCI Friedel-Craft acylation (or C-acylation) 8. Mode - 13 + HCI HCCI Extremely poor yield. Decent yield (0-acylation)
