A: Pentane Explanation: This is a straight-chain alkane with 5 carbon atoms. The word root is 'pent' (for 5 carbons) and suffix is 'ane' (for saturated hydrocarbon). No branching or functional groups ar

A: 2-Methylbutane Step-by-step naming: 1. Main chain has 4 carbons (butane) 2. CH₃ branch at position 2 3. Branch is methyl group 4. Format: position-branch name-main chain name

A: 1. Choose the longest carbon chain as main chain 2. Number from the end that gives branches the lowest position numbers 3. If same position from both ends, choose the end giving second branch lower nu

A: Electrochemistry is the branch of chemistry that deals with the study of processes that produce electricity through chemical reactions and use electricity to bring about chemical reactions. It involve

A: The two main types of electrochemical cells are: 1. Galvanic cells - convert chemical energy into electrical energy (e.g., Daniel cell), 2. Electrolytic cells - use electrical energy to bring about ch

A: In a Daniel cell: Anode = Zinc electrode (where oxidation occurs: Zn → Zn²⁺ + 2e⁻), Cathode = Copper electrode (where reduction occurs: Cu²⁺ + 2e⁻ → Cu). Remember: Anode is negative, cathode is positi

A: 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

A: 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

A: 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
