Alcohols Phenols and Ethers - Online Test

Answer : Option C
Explaination / Solution:


Glycerol and trihydroxypropane are common names. The IUPAC name is propane-1,2,3-triol. The common name glycerol comes from the root glyco- which means sweet. Glucose, glycogen, and glycerin (another name for glycerol) have the same etymology.

Answer : Option B
Explaination / Solution:

Secondary alcohols are oxidized to ketones. The oxidation of isopropyl alcohol by potassium dichromate (K2Cr2O7) gives acetone, the simplest ketone: Unlike aldehydes, ketones are relatively resistant to further oxidation, so no special precautions are required to isolate them as they form.

Answer : Option A
Explaination / Solution:

Lowest set of locants: The lowest set of locants is defined as the set that, when compared term by term with other locant sets, each cited in order of increasing value, has the lowest term at the first point of difference. With regard to numbering of locants, simple prefixes (simple substituent groups consisting of just one part that describes an atom, or group of atoms as a unit, for example methyl and ethoxy) are considered together with equal seniority: Therefore, the given compound is named as 2-ethoxy-1,1-dimethylcyclohexane rather than 1-ethoxy-2,2-dimethylcyclohexane since the locant set ‘1,1,2’ is lower than ‘1,2,2’.

Answer : Option C
Explaination / Solution:

Longest chain has three carbons and at 2^nd position both –OH and –CH₃ group are attachted.

Answer : Option A
Explaination / Solution:



Anisole, or methoxybenzene, is an organic compound with the formula CH3OC6H5. It is a colorless liquid with a smell reminiscent of anise seed, and in fact many of its derivatives are found in natural and artificial fragrances.

Answer : Option D
Explaination / Solution:

C₆H₅OCH₂CH₃ is ethyl phenyl ether or phenetole is an organic compound that is an ether. Ethyl phenyl ether has the same properties as some other ethers, such as volatility, explosive vapors, and the ability to form peroxides.

IUPAC name : Ethoxybenzene 

Other names : Phenetole, Ethyl Phenyl Ether

Answer : Option A
Explaination / Solution:

Meta-Cresol (m-cresol) also 3-methylphenol, is an organic compound with the formula CH3C6H4. It is a colourless, viscous liquid that is an intermediate in the production of other chemicals.

Answer : Option A
Explaination / Solution:

• Catechol is o- hydroxyl phenol or Catechol also known as pyrocatechol or 1,2- dihydroxybenzene,
• Resorcinol is m- hydroxyphenol
• Quinol is p-hydroxyphenol or benzene-1,4-diol is an aromatic organic compound that is a type of phenol, a derivative of benzene.

Answer : Option A
Explaination / Solution:

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 an ester or lactone gives a tertiary alcohol in which two alkyl groups are the same, and the addition of a Grignard reagent to a nitrile produces an unsymmetrical ketone via a metalloimine intermediate.
