SCH4U ORGANIC STRUCTURE AND BONDING Exercise (Tej 2015A) This exercise is aimed at illustrating the principles of bonding in organic chemistry by having you construct molecular models of various carbon compounds. Pay particular attention to the atomic arrangements that constitute functional groups. In every case, be sure to adhere to the stable octet rule as it applies to the bonds around the carbon atoms. Short connectors are used to represent single bonds, while the longer connectors facilitate the construction of multiple bonds. PROCEDURE: Put in chart form! 1. Please construct molecular models of the following saturated hydrocarbons. Draw a diagram of the molecular structure for each molecule in your notebook. Be sure to include the IUPAC name below the sketch for each molecule. (a) 2,2-dimethylpentane (b) 1,2-dichloropropane ) cyclopentane (d) 1-bromo-3-chloroheptane (C) 2-iodo-3-methyloctane ( 1,1,2-tribromopentane Please use the molecular model kits to create models of the following unsaturated hydrocarbons, drawing with the correct geometry of the structures in the diagrams that you sketch and label. (a) 1-pentene * cis-1,2-dibromobutene *3-ethyl-trans-1,2-dichloropentene (d) chlorocyclohexene (@) trans-2-hexene * 1-chloroethyne 2. 3. Please construct models of the following molecules, taking care to record the geometric shape around the central carbon atom of the functional group. (a) 2-propanol (b) ethyl-propyl ether methanal (d) 3-methyl-octanoic acid (@) 1-butanol (n-butanol) + 1-amino-3-iodohexane DISCUSSION: 1. How many structural isomers exist for the compound CsH2? Please DRAW each isomer's structural diagram, and write the appropriate systematic name for each isomer under the respective diagram. 2. Please describe each term below and give an example for each pair of (a) structural isomers. (b) geometric isomers. 3 Please correct the following names for organic compounds, and write the reason for the (a) 1-hexanone (b) 2-ethyloctane (e) cis-2,2,3-trichloroheptene 4. Draw two repeating units each and explain why substituted alkanes (alkyl halides) have higher boiling points than alkanes with same number of carbons. 5. 5. Please complete the chart on the back of this page. Please write conclusions for this exercise
