Which of the following reactions gives a secondary alcohol?
Complete step by step answer:
Formaldehyde on reaction with Grignard reagent followed by acid hydrolysis gives primary alcohol. All other aldehydes on reaction with Grignard reagent followed by acid hydrolysis give secondary alcohol.
What are the examples of secondary alcohol?
An example of a secondary alcohol is:
- A. 1-propanol.
- B. 2-propanol.
- C. 1,2-propanol.
- D. 1,2,3- propanol.
Which one of the following is a secondary alcohol formula?
2-methyl-2-propanol.
What makes a secondary alcohol?
Definition. A secondary alcohol is a compound in which a hydroxy group, ‒OH, is attached to a saturated carbon atom which has two other carbon atoms attached to it.
Which one of the following reactions will produce tertiary alcohol?
Ethyl acetate (an ester) will form tertiary alcohol on reaction with excess CH3MgI.
In which of the following reaction secondary alcohol is formed as major product?
hence,using grignard reagent,secondary alcohol is produced in first reactions.
Which of the following is a secondary allylic alcohol?
But-3-en-2-ol is a secondary allylic alcohol.
Secondary allylic alcohols are the allylic alcohols in which the carbon atom is linked with the double bond as well as to another carbon and also one hydrogen.
How do you identify a secondary alcohol?
A secondary alcohol is identified by the color change with the acidified potassium dichromate(VI) solution and the absence of a color change with the Schiff’s reagent might.
What is difference between primary secondary and tertiary alcohol?
Alcohols are organic molecules containing a hydroxyl functional group connected to an alkyl or aryl group (ROH). If the hydroxyl carbon only has a single R group, it is known as primary alcohol. If it has two R groups, it is a secondary alcohol, and if it has three R groups, it is a tertiary alcohol.
Which of the following is a secondary alcohol cyclohexanol?
In cyclohexanol, the hydroxyl −OH group is attached to one of the carbon atoms of the cyclohexane. Thus, the carbon atom bearing a hydroxyl group is secondary carbon. Thus, cyclohexanol is a secondary alcohol. So, the correct answer is “Option B”.
What is primary and secondary alcohol?
A primary alcohol is an alcohol in which the hydroxy group is bonded to a primary carbon atom. … In contrast, a secondary alcohol has a formula “–CHROH” and a tertiary alcohol has a formula “–CR2OH”, where “R” indicates a carbon-containing group. Examples of primary alcohols include ethanol and 1-butanol.
Is cyclohexanol a secondary alcohol?
Cyclohexanol is an alcohol that consists of cyclohexane bearing a single hydroxy substituent. … It is a secondary alcohol and a member of cyclohexanols.
Is 1 butanol a secondary alcohol?
Isopropyl alcohol is a secondary (2º) alcohol, and is easily oxidized by mild oxidizing agents. 1-Butanol, or butyl alcohol, is a four-carbon chain, with the OH group on an end carbon. It is used as a solvent and a paint thinner, and has some potential use as a biofuel.

What is the functional group of secondary alcohol?
A secondary alcohol has the hydroxyl group on a secondary (2°) carbon atom, which is bonded to two other carbon atoms. Similarly, a tertiary alcohol has the hydroxyl group on a tertiary (3°) carbon atom, which is bonded to three other carbons. Alcohols are referred to…
