Phenols (pKa ≈ 10) are more acidic than other alcohols, so they are easily deprotonated bysodium hydroxide or potassium hydroxide. The anions of phenols (phenoxide ions) can beused in the Williamson ether synthesis, especially with very reactive alkylating reagents suchas dimethyl sulfate. Using phenol, dimethyl sulfate, and other necessary reagents, show howyou would synthesize methyl phenyl ether.

When cis-4-chlorocyclohexanol is treated with sodium hydroxide in ethanol, it gives mainly the substitution product trans-1,4-cyclohexanediol (1). Under the same reaction conditions, trans-4-chlorocyclohexanol gives 3-cyclohexenol (2) and the bicyclic ether (3). (a) Propose a mechanism for formation of product (1), and account for its configuration. (b) Propose a mechanism for formation of product (2). (c) Account for the fact that the bicyclic ether (3) is formed from the trans isomer but not from the cis isomer.
