CONTENTS ◼Properties ◼Preparation ◼Reactions of alkynes ⚫Electrophilic additions to alkynes ⚫Reduction & Oxidation of alkynes ⚫Special reactions of terminal alkynes
Sec 1 Introduction Properties Alkynes contain a triple bond. General formula is C,H2m2. Two elements of unsaturation for each triple bond. Some reactions are like alkenes:addition and oxidation. Some reactions are specific to alkynes
