Need help?! I.Isomers of DichloropentaneA. Structural IsomersFor each unbranched structural isomer of dichloropentane, fill in the table on page 2 as described below.1. Write a condensed structural formula. List isomers with no stereocenters first, isomers with onestereocenter second and isomers with two stereocenters last.2. Write the IUPAC name.3. Give the number of stereocenters. Go back to the structural formula and put an asterisk next to eachstereocenter.4.Construct and use a molecular model to determine the answer to the following questions.Is there a plane of symmetry in any conformation of the molecule? State yes (Y) or no (N).а.b. Is the molecule chiral (C) or achiral (A)?Is the molecule optically active (A) or optically inactive (I)?с.d. How many stereoisomers (one or more) correspond to the structure?B. StereoisomersUsing the molecular model for each structural isomer in Part A, proceed as follows to study thestereoisomers corresponding to each structure.If the molecule is chiral, construct its mirror image model and verify that the two arenonsuperimposable.1.2. If the molecule has two stereocenters, generate a diastereomer by interchanging any two groups on onestereocenter; construct its mirror image. Inspect the stereochemical relationships among the fourstereoisomeric models you have constructed.3. Use pages 3 and 4 to make a drawing* of each different isomer (no repeats) you have found. Group thestereoisomers of each structure together and put them in the same order as you have listed them onpage 2. There may be only one drawing to make for a given structural isomer (achiral molecule); twodrawings (one stereocenter); or four drawings (two stereocenters). The existence of a meso form wouldreduce the number of stereoisomers.4. Assign an R or S absolute configuration to each stereocenter in each drawing.* Draw the longest carbon chain hortizontal. Use perspective and a staggered conformation to show theconfigurations at stereocenters; condense the rest of the structure. Plane ofSym-metry?

C. Nomenclature of Cylic Alkanes: If a ring is present in a molecule, the ring is almost always considered the parent chain. Use the word cyclo as a prefix before the alkane name to indicate it is a cyclic parent chain Number the carbons that bear substituents starting with one, and number around the ring towards the closest carbon that bears another substituent group to give all substituents lowest possible numbering. If there are two or more substituents, use alphabetical order to determine where to start numbering. Critical Thinking Question (CTQ): 11. Give the correct IUPAC name for the remaining three compounds below. H,C CH-CH, l-isopropyl-3-methylcycloherane 12. Draw the structures that correspond to the following names: a. 3-ethylheptane b. 1,1-diethylcyclopropane c. 4-sec-butyl-1-isobutyl-2-methylcylcohexane 13. Mono-substituted cycloalkanes do not include the "1" locant. Thus, 1-methylcyclohexane is inaccurate. Draw methylcyclohexane; explain why adding a locant does not add…
1,2-ditert-butylcyclohexane is an interesting case of a conformational study. The cis isomer is more stable than the trans isomer, although the trans isomer presents a conformer with both substituents in equatorial positions. In order to analyze this fact:a. Draw the conformational equilibrium of both compounds. Explain using and drawing the structures why this difference happens (the one described above). b. In the trans isomer, the di-axial conformation is 25.9 kJ / mol more stable than the di-equatorial. Calculate the energy of the di-equatorial conformation.
