1. What is an alkene and its general formula? - Ans .It is an unsaturated hydrocarbon with a least one C=C bond. General formula is CnH2n 2. What is a sigma bond? σ - Ans .single covalent bond formed when two s orbitals overlap. High electron density 3. What is a pi bond? - Ans .sideways overlap of p orbitals that occur in a double or triple bond. Much weaker than sigma, low bond enthalpy and lower electrostatic attraction 4. Is an alkane or an alkene more reactive? - Ans .Alkene. cont...

Addition - ANSWERA reaction involving an increase in the number of groups attached to the alkene and a decrease in the number Regiochemistry - ANSWERThe orientation of a chemical reaction on an unsymmetrical substrate. In additions to alkenes, the regiochemistry of the addition involves which part of the reagent adds to which end of an unsymmetrical alkene. Regioselective reaction - ANSWERA reaction in which one direction of bond making or bond breaking occurs preferentially over all other...
