Be prepared to draw displayed formulas (showing all bonds) and molecular formulas for the first four alkenes.

While alkenes can burn, they often undergo incomplete combustion , resulting in a smoky flame due to unburnt carbon particles. Key Concepts for Exam Success chemsheets 1232 answers

Alkenes are a homologous series of that contain at least one carbon-to-carbon double bond ( Be prepared to draw displayed formulas (showing all

). This double bond is their functional group and is responsible for their high chemical reactivity compared to alkanes. The general formula for alkenes is CnH2ncap C sub n cap H sub 2 n end-sub Key Examples: Common alkenes include ethene ( C2H4cap C sub 2 cap H sub 4 ), propene ( C3H6cap C sub 3 cap H sub 6 ), and butene ( C4H8cap C sub 4 cap H sub 8 This double bond is their functional group and

in the presence of a catalyst (like nickel) converts an alkene into an alkane.
