WebCyclopropane is necessarily planar (flat), with the carbon atoms at the corners of an equilateral triangle. The 60º bond angles are much smaller than the optimum 109.5º angles of a normal tetrahedral carbon atom, and the resulting angle strain dramatically influences the chemical behavior of this cycloalkane. Phenol ethers can be synthesized through an acid-catalyzed condensation of phenols and an alcohol. Phenols include phenol itself, benzenediols, polyphenols, and other phenol-derived molecules. However, this synthesis risks the self-condensation of alcohol itself (e.g. ethanol self-condenses to form diethyl ether). A more common and higher-yielding rea…
