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.

Note, only a total of six structures should be written on your paper. Also, include hydrogen atoms wherever are substituents on all of your chair conformers. Note, a table listing is a requirement for this problerm Answer (Total # of Conformers of A): 6-Levels of stability from the most stable of A: The sixth most stable conformer of A: 9-Levels that is unstable from the most unstable of A 5-levels of instability from the most unstable of A 스 Conformers of A that is representative of B:
New hydrocarbon compounds K, L, M and N have been formed from an organic reactions in Dr. Meredith laboratory. She found that compound K and L with molecular formula (C;H14) are unsaturated hydrocarbons with positional isomerism. Meanwhile, the reaction of hydrocarbon from compound M produces carbon dioxide and water when burns in plentiful oxygen. Another observation showed compound N produces three products X, Y and Z when react with chlorine gas in the presence of UV light. Identify the name of unsaturated hydrocarbon compound K and L and draw their possible condensed and skeletal structures. Suggest the IUPAC nomenclature name for compound M and write the complete chemical reaction of compound M when burns in plentiful oxygen. Show the complete mechanism reaction that occur for the formation of products X, Y and Z from compound N.
