OH :ÖH 3²8- TÖ www +N C1 C1 OH 70 7Ö TC1: a) electron withdrawing group, activating towards nucleophilic aromatic substitution b) electron withdrawing group, deactivating towards nucleophilic aromatic substitution c) electron donating group, activating towards nucleophilic aromatic substitution d) electron donating group, deactivating towards nucleophilic aromatic substitution

Question 13 of 17 0.67 / 1 View Policies Show Attempt History Current Attempt in Progress Propose a plausible mechanism for the following transformation. 1) NaH OEt 2) Etl 13.38b Correct. This mechanism begins with deprotonation of the alcohol by the strong base. The resulting alkoxide anion is a strong nucleophile and will undergo an SN2 mechanism with ethyl iodide. 2 v This substitution reaction is expected to be an SN iodide mechanism because the leaving group, II

Stereoisomers of α-bromocinnamic acid: draw the reaction mechiansim with arows for the dehydrobromination of 2,3-dibromo-3-phenylpropanoic acid with ethanol and KOH to produce (Z)-α-bromocinnamic acid and (E)-α-bromocinnamic acid. Also draw the transition state for The (Z)-isomer syn-periplanar transition state and anti-periplanar transition state of the (E)-isomer.
