Because ketones lack the –CHO group required to reduce Tollens’ reagent.
A heterogeneous system with dispersed particles (1–1000 nm) in a dispersion medium. Example: Milk (liquid in liquid)
· Antacids: Neutralize excess acid (e.g., Mg(OH)₂) · Antihistamines: Block histamine receptors to prevent allergy (e.g., cetirizine)
Sugars that can reduce Tollens’ or Fehling’s reagent (have free aldehyde/ketone). Examples: Glucose, fructose, maltose
Due to higher electronegativity of halogens, the bond is polar (partial positive on C, negative on X).
The sum of powers of reactants in the rate law. Determined by experimental data and not from the balanced equation.
· Oxidizing Agent: Substance that gains electrons and undergoes reduction, causing another substance to be oxidized. · Reducing Agent: Substance that loses electrons and undergoes oxidation, causing anoth...
· Half-Reaction Method: Involves balancing the reduction and oxidation half-reactionsseparately.· Ion-Electron Method (or Oxidation-Reduction Method): Balances the redox reaction by dividing it into oxidation and redu...
· The oxidation number is the hypothetical charge that an atom would have if all bonds to atoms of different elements were 100% ionic. · Rules for assigning oxidation numbers help determine whether a species unde...
(a) Select the possible non-metals that can show disproportionation reaction. Ans: One of the reacting compounds must always contain an element that can exist in at least three oxidation states in disproportionation r...
