Alkanes & Alkenes

The video tutorial explains the structure and bonding of alkanes and alkenes. Alkanes are saturated hydrocarbons with single covalent bonds, exemplified by methane and ethane. The general formula for alkanes is CnH2n+2. Alkenes, like ethene and propene, are unsaturated with double covalent bonds and follow the formula CnH2n. The tutorial covers the molecular and structural formulas of these hydrocarbons, emphasizing the pattern in their homologous series.
