4) Identify four functional groups (FG's) and assign the class of compounds for each molecule. 4 points Choose FG's from: Vinyl, allyl, alkynyl, phenyl, benzyl, chloro, bromo, iodo, hydroxyl, alkoxy (ether), amino, mercapto, alkylthio, carbonyl, carboxy, amido, cyano Choose classes from: alkene, alkyne, aromatic compound, alkyl halide, alcohol, ether, amine, thiol, thioether, aldehyde, ketone, carboxylic acid, ester, acyl chloride, amide, nitrile 5) Formulate the nine possible constitutional isomers with the sum formula C7H16. Do not formulate multiple identical structures (deduction!). Hint: There cannot be a double bond, triple bond or ring in the structure! 5 bonus points
