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

Biomolecules Q02: A student is revising concept 1. Which correction is chemically sound?

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

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

DCarbohydrates are polyhydroxy aldehydes or ketones or yield them on hydrolysis.

03Chemistry

Biomolecules Q03: In a standard exam item involving concept 1, which inference is valid?
