Chemistry (General Concepts) MCQs with Answers

One-liner

The hybridization of carbon in methanol (CH₃OH) is sp³ because carbon forms four single (sigma) bonds with surrounding atoms.

One-liner

1 g equivalent weight of Aluminum is equal to 9 g.

One-liner

N₂ (nitrogen gas) is inactive in the infrared spectrum because it is a homonuclear diatomic molecule with no net dipole moment.

One-liner

Ice is an example of a molecular solid because its molecules (H₂O) are held together by intermolecular hydrogen bonds rather than covalent, ionic, or metallic bonds.

One-liner

A covalent bond is formed between two non-metals by the mutual sharing of electrons.

One-liner

When atoms of different elements with different electronegativities share electrons, the bond formed is a polar covalent bond.

One-liner

Dissociation of a solute does not depend on the size of solvent; it depends on the nature of solute, nature of solvent, and temperature.

One-liner

Open chain organic compounds are called aliphatic compounds.

One-liner

The mutually shared pair of electrons that links atoms in a molecule is known as a Covalent Bond.

One-liner

Arene (aromatic hydrocarbons) predominantly undergo substitution reactions rather than addition reactions due to the stability of their aromatic ring.
