Functional GroupsFunctional Groups Functional group- collection of atoms at a site gpwithin a molecule with a common bonding pattern The group reacts in a typical way, generally independent of the rest of the moleculeindependent of the rest of the molecule For example, the double bonds in simple and complex alkenes react with bromine in the same way (See Figure 3 1)(See Figure )Types of Functional Groups : Multiple bbdCarbon Carbon Bonds Alkaneshave only yC-C and C-H single bonds Alkeneshave a C-C Alkeneshave a CC double bond Alkyneshave a C-C triple bondtriple bond Areneshave special bonds that are tdrepresented as alternating single and double C-C bdi ibonds in a six-membered ring Functional Groups with Carbon Singly ddliBonded to an Electronegative Atom Alkyl halide:C bonded to halog
Alkanes & Isomers compounds with same molecular formula Alkanes & Isomers but different arrangement of atoms CH 4 = methane, C 2H 6 = ethane, C 3H 8= propane but different arrangement of atoms pp The molecular formula of an alkane with more than three carbons can give more than one structure C 4 (butane) = butane and isobutane C 5 (pentane) = pentane, 2 …
