Alkenes react with halogens like bromine ( Br2cap B r sub 2 ) or chlorine ( Cl2cap C l sub 2

Always remember that the bromine water test distinguishes between alkanes (no color change) and alkenes (decolorizes). chemsheets 1232 answers

). The reaction with bromine water is a standard test for unsaturation: the orange-brown liquid turns . Reaction with Hydrogen (Hydrogenation): Adding H2cap H sub 2 Alkenes react with halogens like bromine ( Br2cap

They are called "unsaturated" because they do not contain the maximum possible number of hydrogen atoms for the given number of carbons. Core Reactions Covered in Chemsheets 1232 Reaction with Hydrogen (Hydrogenation): Adding H2cap H sub

). 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
