Diazonium salts for phenol preparation are formed by treating an aromatic primary amine with which of the following reagents?
The NCERT text states: 'A diazonium salt is formed by treating an aromatic primary amine with nitrous acid (NaNO2 + HCl) at 273-278 K.'
The preparation of phenol in the laboratory is typically carried out from which type of compounds, as mentioned in the NCERT text?
The NCERT text states: 'In the laboratory, phenols are prepared from benzene derivatives by any of the following methods.'
Which of the following organic functional groups is characteristic of both alcohols and phenols?
The introductory part of the chapter mentions: 'Alcohols and phenols are formed when a hydrogen atom in a hydrocarbon, aliphatic and aromatic respectively, is replaced by –OH group.'
Phenol was first isolated from which natural source in the early nineteenth century?

Which of the following describes an allylic alcohol?
According to the NCERT text, 'Allylic alcohols: In these alcohols, the —OH group is attached to a $sp^3$ hybridised carbon adjacent to the carbon-carbon double bond, that is to an allylic carbon.'
Which of the following compounds is an example of an unsymmetrical ether?
The NCERT states, 'Ethers are classified as simple or symmetrical, if the alkyl or aryl groups attached to the oxygen atom are the same, and mixed or unsymmetrical, if the two groups are different. Diethyl ether, $C_2H_5OC_2H_5$, is a symmetrical ether whereas $C_2H_5OCH_3$ and $C_2H_5OC_6H_5$ are unsymmetrical ethers.' In option o3 ($C_2H_5OCH_3$), the two alkyl groups attached to the oxygen (ethyl and methyl) are different, making it an unsymmetrical ether.
Phenols are classified as mono-, di-, or trihydric based on:
The NCERT states, 'Alcohols and phenols may be classified as mono–, di–, tri- or polyhydric compounds depending on whether they contain one, two, three or many hydroxyl groups respectively in their structures'.
What is the IUPAC name for 'm-Cresol'?
According to the NCERT Table 7.1, the common name 'm-Cresol' corresponds to the IUPAC name '3-Methylphenol'.
How are ethers generally classified according to the NCERT text?
The NCERT Summary states, 'Ethers are classified on the basis of groups attached to the oxygen atom.'
Which of the following statements correctly describes a primary alcohol?
The NCERT text classifies primary, secondary, and tertiary alcohols based on whether the -OH group is attached to a primary, secondary, or tertiary carbon atom, respectively. A primary carbon is bonded to one or no other carbon atoms.
