Q. Explain the structure of Alkenes?
Ans.
Alkenes have the general formula CnH2n. Therefore, for every n carbon atoms, there are 2n hydrogen atoms.
Alkenes have C = C double bonds and are therefore unsaturated.
Ethene (also called ethylene) and is the first member of the alkene series:
Ethylene is made by passing ethanol vapor over heated aluminum oxide which acts a catalyst.
Q. Structure of Covalent Bonds? Ans. A covalent bond forms between elements that are near each other in the periodic table While an ionic bond involves an exchange of e
