Cyclohexane is a saturated hydrocarbon, containing only single bonds.

2-Pentanol has the hydroxyl group attached to a secondary carbon, making it a secondary alcohol.

Hydrochloric acid (HCl) is a strong acid that completely dissociates in water.

Hydrochloric acid (HCl) is a strong acid.

Formic acid is considered a stronger carboxylic acid compared to the others listed.

Polyvinyl chloride (PVC) is a synthetic polymer commonly used in construction and plumbing.

Bakelite is a thermosetting polymer, while the others are thermoplastics.

Colligative properties depend on the number of solute particles in a solution, and boiling point elevation is one such property.

Nylon-6,6 is a condensation polymer formed by the reaction of hexamethylenediamine and adipic acid.

Starch in water is a lyophilic colloid as it has a strong affinity for the solvent.

Lightning is an example of plasma, which is a state of matter consisting of ionized gas with free electrons.

Plasma is a state of matter where gases are energized until atomic electrons are no longer associated with the nucleus, as seen in lightning.

Alkanes are saturated hydrocarbons with the general formula CnH2n+2. C3H8 (propane) fits this formula.

Propene is an alkene, characterized by a carbon-carbon double bond.

Propene is an alkene, characterized by a carbon-carbon double bond.

Butyne is an alkyne, characterized by a triple bond between carbon atoms.

Physisorption involves weak Van der Waals forces, and the adsorption of water on silica gel is a classic example of this type of adsorption.

Not all p-block elements are metals; many are nonmetals and metalloids.

Solids are not highly compressible; they have a definite shape and volume, and their particles vibrate in fixed positions.

Transition metals generally have high density, not low density.

Aldehydes contain the functional group -CHO, which is characterized by a carbonyl group (C=O) bonded to a hydrogen atom.

P2O5 is the most acidic oxide among the given options, as it forms phosphoric acid in water.

Formic acid (HCOOH) is the strongest carboxylic acid among the given options due to the presence of a hydrogen atom directly attached to the carbonyl carbon, which increases its acidity.

CN- is a strong field ligand that causes a large splitting of d-orbitals, leading to low-spin complexes.

Dialysis is used to purify colloidal solutions by allowing the solvent and small solutes to pass through a semi-permeable membrane while retaining the colloidal particles.

Electrophoresis is used to stabilize colloidal solutions by applying an electric field to separate charged particles.

Water (H2O) has a polar covalent bond due to the difference in electronegativity between hydrogen and oxygen.

Water (H2O) has a polar covalent bond due to the difference in electronegativity between hydrogen and oxygen.

Neodymium (Nd) and Plutonium (Pu) are both f-block elements.

Lanthanum (La) and Cerium (Ce) are both f-block elements, belonging to the lanthanide series.
