Reactivity of alcohols
WebTertiary alcohols are more reactive because the increased number of alkyl groups increases + I effect. So, the charge density on carbon atom increases and hence around oxygen atom. This negative charge density tryna push the lone pairs on oxygen atom away. So, the oxygen atom wanted to leave the carbon atom as soon as possible. WebJun 17, 2015 · The most common protecting group for alcohols is silyl ethers.They are easily formed by treating alcohols with R3SiCl in the presence of base, and then easily removed with a source of fluoride ion F(-) since Si-F bonds are very strong.

WebJan 23, 2024 · Reactivity of Alcohols. The functional group of the alcohols is the hydroxyl group, –OH. Unlike the alkyl halides, this group has two reactive covalent bonds, the C–O bond and the O–H bond.

For example, primary alcohols contain two α – hydrogens and can lose one of them to form aldehyde or it can lose both hydrogens to give carboxylic acid. Thus, the presence of α – hydrogen plays an important role. csf proteomicsWebAlcohol relative reactivity order : 3 o > 2 o > 1 o > methyl.
