Secondary Alcohols (Isopropyl Alcohol) Secondary alcohols are having the carbon atom of the hydroxyl group. That has two alkyl groups on either side. The two alkyl groups exist may be either structurally identical or even different. Isopropyl alcohol also popular as isopropanol or 2-propanol or rubbing alcohol.

In tertiary alcohol, − O H group is attached to a C atom which itself is attached to 3 other C atoms. Thus, ( C H 3 ) 3 − C − O H is tertiary alcohol. The general formula of primary, secondary and tertiary alcohol are − C H 2 O H ; − C H R O H ; − C R 2 O H respectively.

The carbonyl carbon is the one that finally bears the –OH group in the product; here the number of hydrogen defines the alcohol as primary, secondary, or tertiary. 4) Reduction of Carbonyl Compounds. We can also get alcohols by the reduction of aldehydes and ketones. We can reduce aldehydes to primary alcohols and ketones to secondary alcohols.

Arrange tghe following in the increasing order of (1) boiling points, (2)solublity, (3)melting point. Primary Alcohols, Secondary Alcohols, Tertiary Alcohols, Phenols ...

Application : It is used to differentiate primary, secondary and tertiary alcohols. On adding the alcohol to Lucas reagent, a tertiary alcohol reacts immediately forming a ppt of alkyl chloride. If the ppt. appears after few minutes, the alcohols is secondary. If no ppt, is obtained in cold the alcohol is primary.

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 of Grignard Reagent with aldehyde leads to formation of a primary alcohol. The reaction of Grignard Reagent with ketone leads formation of a secondary alcohol.

Which among the following compounds will give a secondary alcohol on reacting with Grignard reagent followed by acid hydrolysis? I. H C H O II. C 2 H 5 C H O III. C H 3 C O C H 3 IV. R C O O C 2 H 5 the correct option is:

On catalytic dehydrogenation, p rimary alcohols give aldehydes, secondary alcohols give ketones and t ertiary alcohols give alkene. Primary and secondary alcohols show a type of beta-elimination in which − O H group from alfa and hydrogen from beta carbon.

Arrange the following alcohols in the increasing order of their acidic strength. a) 2-butanol b) methyl alcohol c) 1-propanol d) 2-methyl-2-propanol

The given alcohol is _____ (primary/ secondary) alcohol. (If your answer is primary type 1 else 2)
