What is a substitution reaction? Give an example with a balanced chemical equation.
Answer
A substitution reaction is a chemical reaction in which an atom or group of atoms is replaced with another atom or group of atoms in a compound. Example: CH₄ + Cl₂ → CH₃Cl + HCl (in presence of sunli…
Define addition reactions and explain why only unsaturated compounds undergo such reactions.
Answer
Addition reactions are reactions in which unsaturated organic compounds with double or triple bonds combine with certain molecules to form saturated compounds. Only unsaturated compounds undergo addi…
Complete the equation and name the product: CH₂=CH₂ + Cl₂ → ?
Answer
CH₂=CH₂ + Cl₂ → CH₂Cl-CH₂Cl Product: 1,2-dichloroethane (ethylene dichloride) This is an addition reaction where chlorine adds across the double bond of ethene to form a saturated dichloride compoun…
What is polymerization? Distinguish between addition and condensation polymerization with examples.
Answer
Polymerization is the process by which simple molecules (monomers) join together to form large complex molecules (polymers). Addition Polymerization: - Monomers add repeatedly without elimination of …
Name the monomer and write the polymerization reaction for PVC (Polyvinyl Chloride).
Answer
Monomer: Vinyl Chloride (CH₂=CHCl) Polymerization reaction: nCH₂=CHCl → [-CH₂-CHCl-]ₙ PVC Uses of PVC: Manufacture of pipes, plastic furniture, coating of electric conductors, etc.
What is thermal cracking? Write the equation for thermal cracking of propane.
Answer
Thermal cracking is the process where hydrocarbons with high molecular weight decompose into hydrocarbons with lower molecular weight when heated in the absence of air. Thermal cracking of propane: C…
Write the general combustion reaction for hydrocarbons and complete: 2C₄H₁₀ + 13O₂ → ?
Answer
General combustion reaction: Hydrocarbon + O₂ → CO₂ + H₂O + Heat + Light Completed equation: 2C₄H₁₀ + 13O₂ → 8CO₂ + 10H₂O + Heat All hydrocarbons on burning give the same products: carbon dioxide, w…
How is methanol prepared industrially? Write the equation and mention its uses.
Answer
Industrial preparation of methanol: CO + 2H₂ → CH₃OH (catalyst, 573K) Methanol (CH₃OH) is also called wood spirit. Uses: - Manufacturing varnish and paint - Manufacture of formic acid and formaldehy…
