Aromatic Compounds | MCQs

Explanation

Sulfuric acid (H₂SO₄) is called the "King of Chemicals" or "King of Compounds" due to its wide use in industries like fertilizers, batteries, and detergents.

It plays a key role in chemical manufacturing.

It is often used to measure a country's industrial strength.

Explanation

Ethyl alcohol, or ethanol, is commonly used in perfumes as a base solvent.

It helps dissolve fragrance oils and allows the scent to disperse evenly when applied.

Explanation

This is done through an electrophilic attack on the aromatic ring with the help of a carbonation.

The Friedel-Crafts alkylation reaction is a method of generating alkylbenzenes by using alkyl halides as reactants.

The Friedel-Crafts alkylation reaction of benzene is illustrated below.

Explanation

Nitrobenzene reacts slower than benzene in electrophilic substitution due to the electron-withdrawing nitro group.

The NO₂ group deactivates the benzene ring, making it less reactive toward electrophiles.

Explanation

 An aromatic alcohol is an alcohol where the hydroxyl group (-OH) is attached to a carbon atom that is part of an aromatic ring (like benzene).

Benzyl alcohol has the chemical formula C6H5CH2OH,

Indicating that the -OH group is attached to a carbon atom that is part of a benzene ring. 

Explanation

 In aromatic sulfonation, sulfur trioxide (SO3) is the actual attacking species, reacting with the aromatic ring to form a sulfonic acid. 

Explanation

Benzene is the archetypical aromatic compound.

It is planar, bond angles=120º, all carbon atoms in the ring are sp2 hybridized, and the pi-orbitals are occupied by 6 electrons.

Explanation

Explanation

• Phenylamine (aniline) is a crucial starting material for the production of many dyes, including acid dyes, basic dyes, and direct dyes.
• These dyes are used to color a wide range of materials, such as fabrics, leather, and paper.
