why do tertiary alcohols dehydrate faster milk

ALCOHOL (beverage based on ethanol) – Dr Rajiv Desai

6/24/2014Structure of Alcohols: The structure of an alcohol resembles that of water as seen in the figure below Water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water

Alcohol Reactivity

When an alcohol is treated with sodium hydroxide the following acid-base equilibrium occurs Most alcohols are slightly weaker acids than water so the left side is favored R–O–H + Na (+) OH (–) R–O (–) Na (+) + H–OH The elimination of water from an alcohol is called dehydration Recalling that water is a much better leaving group

Synthesis of Alcohols

Alcohols can be prepared by the hydration of alkenes or by the reduction of aldehydes ketones acids and esters The elements of water can be added to the double‐bonded carbons of an alkene in either a Markovnikov's or an anti‐Markovnikov's manner As shown in the following figure a hydrogen ion catalyzes the Markovnikov's addition
