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.

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.

The mass of an electron is significantly less than that of protons and neutrons.

The electron has the least mass compared to protons and neutrons.

Condensation is the process where gas changes to liquid.

Free expansion is an irreversible process as it occurs without any external pressure acting on the gas.

An isochoric process is one that occurs at constant volume.

The azimuthal quantum number (l) describes the shape of an orbital.

H2O → H2 + O2 involves the oxidation of water to hydrogen and oxygen, making it a redox reaction.

In the reaction Fe2O3 + 3CO → 2Fe + 3CO2, iron (Fe) is reduced as it gains electrons from carbon monoxide (CO).

0.1 M glucose is a non-electrolyte and does not dissociate, thus it has the highest freezing point compared to the ionic solutions.

Carbon (C) acts as a reducing agent as it donates electrons to reduce Fe2O3 to Fe.

Carbon (C) acts as a reducing agent as it donates electrons to reduce Fe2O3 to Fe.

Carboxylic acids are more acidic than alcohols due to the resonance stabilization of their conjugate base, making the statement 'They are less acidic than alcohols' incorrect.

Not all coordination compounds are colored; the color depends on the nature of the metal and the ligands involved. Some coordination compounds can be colorless.

Adsorption is a surface phenomenon as it occurs at the interface between phases.
