A Williamson ether synthesis is shown below. 2-naphthol in the
presence of sodium hydroxide undergoes a deprotonation to give the
alkoxide shown below. 1-Bromooctane is then added and undergoes a
nucleophilic substitution by SN2 mechanism. Add curved arrows to
demonstrate the SN2 substitution described.

Map Propiophenone with 1-methylcyclopentanecarbaldehyde in the presence of sodium hydroxide undergoes a crossed aldol reaction
Map Propiophenone with 1-methylcyclopentanecarbaldehyde in the presence of sodium hydroxide undergoes a crossed aldol reaction. The aldol condensation is complete once the aldol product above undergoes an elimination upon heating. Complete the mechanism for the reaction by adding missing bonds, and curved arrows. Do not delete any of the predrawn bonds, atoms and nonbonding electrons.
