Draw the structure of an eight-carbon alkene that would yield the following compound (and no others) after treatment with ozone followed by dimethyl sulfide.<\/p>\n\n\n\n
The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n To determine the correct structure of an eight-carbon alkene<\/strong> that produces a single product<\/strong> after ozonolysis followed by dimethyl sulfide (DMS)<\/strong>, we must understand the ozonolysis mechanism.<\/p>\n\n\n\n The correct alkene<\/strong> is:<\/p>\n\n\n\n 4-octene (CH\u2083CH\u2082CH=CHCH\u2082CH\u2082CH\u2083)<\/strong><\/p>\n\n\n\n Ozonolysis cleaves the C=C double bond<\/strong>, converting each carbon of the double bond into a carbonyl group (C=O)<\/strong>. When using dimethyl sulfide (DMS)<\/strong> as the reducing agent, the ozonide intermediate is reduced to aldehydes or ketones, depending on substitution.<\/p>\n\n\n\n Let\u2019s analyze 4-octene<\/strong>:<\/p>\n\n\n\n CH\u2083CH\u2082CH=CHCH\u2082CH\u2082CH\u2083<\/strong><\/p>\n\n\n\n Carbon numbering: The double bond is between carbon 4 and carbon 5.<\/p>\n\n\n\n Ozonolysis cleaves the double bond and oxidizes both carbons into aldehydes or ketones<\/strong>:<\/p>\n\n\n\n From 4-octene:<\/p>\n\n\n\n CH\u2083CH\u2082CH\u2082\u2013CHO<\/strong> (butanal) \u2705 Both products are butanal<\/strong>, so only one compound<\/strong> is formed, making this the correct answer.<\/p>\n\n\n\n Ozonolysis is a reaction where alkenes are cleaved by ozone (O\u2083), breaking the carbon\u2013carbon double bond and forming carbonyl-containing compounds (aldehydes or ketones). The actual outcome depends on the substituents attached to the double bond and the work-up conditions. When using a reducing agent like dimethyl sulfide (DMS)<\/strong> in the second step, ozonolysis results in aldehydes or ketones, not carboxylic acids.<\/p>\n\n\n\n The problem specifies an eight-carbon alkene<\/strong> that yields only one product<\/strong> after ozonolysis with DMS. This implies the double bond must be symmetrically placed so that both halves of the molecule are identical<\/strong> after cleavage. If the alkene were asymmetrical, ozonolysis would produce two different products<\/strong>, violating the question’s constraint.<\/p>\n\n\n\n Among eight-carbon alkenes, 4-octene<\/strong> is symmetrically substituted. It has the structure CH\u2083CH\u2082CH=CHCH\u2082CH\u2082CH\u2083<\/strong>, with the double bond between carbon 4 and carbon 5. Upon ozonolysis, the double bond breaks, and each carbon forms a C=O<\/strong> group. In this case, both fragments are butanal (CH\u2083CH\u2082CH\u2082CHO)<\/strong>, resulting in just one unique product.<\/p>\n\n\n\n Other alkenes like 1-octene<\/strong> or 2-octene<\/strong> would yield two different products (like formaldehyde and heptanal or propanal and pentanal) and thus do not meet the requirement.<\/p>\n\n\n\n Therefore, 4-octene<\/strong> is the only eight-carbon alkene that gives one ozonolysis product \u2014 butanal<\/strong> \u2014 when treated with ozone and dimethyl sulfide.<\/p>\n","protected":false},"excerpt":{"rendered":" Draw the structure of an eight-carbon alkene that would yield the following compound (and no others) after treatment with ozone followed by dimethyl sulfide.
