Oxidation of Alcohols

Conversion of Alcohols – Making of Ketones Tertiary alcohol: Lucas test is based on the difference in reactivity of primary secondary and tertiary alcohols with hydrogen chloride In the Lucas test the alcohol is treated with Lucas reagent (concentrated HCl and ZnCl 2) Turbidity is produced as halides of the substituted alcohol are

Difference Between Primary Secondary and Tertiary

1/20/2018Main Difference – Primary vs Secondary vs Tertiary Amines An amine is a derivative of ammonia It is composed of one or more alkyl groups which replace the hydrogen atoms in ammonia (NH 3) molecule Therefore the alkyl group is directly bonded to the nitrogen atom According to the number of alkyl groups that have been attached to the nitrogen atom amines are categorized into three broad

Which alcohol reacts more readily with sodium metal

3/9/2016Clearly the primary alcohol is the most water-like solvent Thus a primary alcohol should be most labile to alkali metal You know the result of the reaction of sodium metal with water Methyl alcohol is also VERY reactive towards sodium metal Ethyl alcohol reacts more slowly but is still zippy Above ethyl alcohol propyl alcohol and butyl alcohol are very sluggish and will likely not

Tertiary Alcohol

However we were frustrated with unexpectedly low reactivity of 37 The tertiary alcohol 37 was completely unreactive under Yamaguchi Shiina 61 Kita 62 and Steglich 63 conditions Esterification of 37 with the thioester 48 under the influence of Ag(OCOCF 3) or Cu(OTf) 2 64 65 was also ineffective

Grignard Reaction

The Grignard Reaction is the addition of an organomagnesium halide (Grignard reagent) to a ketone or aldehyde to form a tertiary or secondary alcohol respectively The reaction with formaldehyde leads to a primary alcohol Grignard Reagents are also used in the following important reactions: The addition of an excess of a Grignard reagent to

Tertiary Alcohol

Inductive effect is an increase in stability due to electron donation from surrounding alkyl groups In this particular reaction the SN1 mechanism is most likely as the inductive effect will be greatest (tertiary alcohol three alkyls attached to the central carbon) thus producing a stable carbocation intermediate
