Purification and Characterisation of Organic Compounds Q01: Which statement about concept 1 is correct?

ACrystallisation purifies solids based on differential solubility.

BIt is defined as complete loss of all protons from an atom.

CIt requires conversion of every substance into a noble gas.

DIt is independent of composition, structure, concentration and temperature in every case.

02Chemistry

Purification and Characterisation of Organic Compounds Q02: A student is revising concept 1. Which correction is chemically sound?

AIt occurs only by peptide bond formation in proteins.

BIt is explained solely by colour change without particles or bonds.

CIt always has zero relation to electrons, ions or molecular structure.

DCrystallisation purifies solids based on differential solubility.

03Chemistry

Purification and Characterisation of Organic Compounds Q03: In a standard exam item involving concept 1, which inference is valid?

AIt means all reactions become spontaneous without conditions.

BIt is a nuclear fission rule rather than a chemistry principle.
