11.15A Ethers by Intermolecular Dehydration of Alcohols

西华大学：《电力电子学》章程教学实验指导书（共四个实验）

Alcohols are compounds whose molecules have a hydroxyl group attached to a saturated carbon atom

No addition of bromine No oxidation No hydroation Slow addition at high temperature and pressure

Many other pairs of reagents that form cabocations (orcarbocationlike species) may be used as well

一．基因型频率 基因型频率(genotype freguencie)：在同一个基因的座位上，某一种基因型的个体数在总群体中所占的比率。 例：深红虎蛾（Panaxia dominula）

If a chiral atom attached to the carbonyl group, the stereoselectivity of nucleophilic addition follows the Cram’s rule
