The structural formula for n − octyne is to be drawn. The total number of isomers that are possible by moving only the position of the triple bond is to be determined. Concept Introduction: Hydrocarbons are the organic compounds which contain only carbon and hydrogen atoms. Isomers are the compounds which have the same molecular formula but different arrangement of the atoms in space. The structural formula is a two-dimensional representation, which gives the information about the atoms that are bonded together and the atoms which are not bonded. Alkynes are the unsaturated hydrocarbons , which contain at least one triple bond. The general molecular formula for the alkyne is C n H 2 n − 2 .

Question

5. Propose a Synthesis for the molecule below. You may use any starting materials containing 6 carbons or less (reagents that aren't incorporated into the final molecule such as PhзP do not count towards this total, and the starting material can have whatever non-carbon functional groups you want), and any of the reactions you have learned so far in organic chemistry I, II, and III. Your final answer should show each step separately, with intermediates and conditions clearly drawn. H3C CH3

Answer 1

Question

Definition Definition Molecules that have multiple bonds between their carbon atoms. Alkenes are hydrocarbons with a double bond between two adjacent carbon atoms (R 2 C=CR 2 ), whereas alkynes are hydrocarbons with a triple bond between two adjacent carbon atoms R-C=C-R . These two groups are known as unsaturated hydrocarbons. They have fewer hydrogen atoms when compared with alkanes with same number of carbon atoms. The general molecular formula for an unsaturated hydrocarbon can be represented as C n H 2n +2 .
