Question 30 (4 points) Friedel-Crafts alkylation reactions cannot be performed on benzaldehyde because: The aldehyde group is strongly activating, and multiple substitutions occur on the aromatic ring. The aldehyde group gets alkylated instead of the aromatic ring. The aldehyde group attacks the Lewis acid to form an acid-base complex in which the aromatic ring is strongly deactivated The aldehyde group is moderately deactivating preventing any substitution on the aromatic ring. Question 31 (4 points) Which of the following produces no...
