The product of the following reaction sequence is nervonic acid.What is the structure of nervonic acid?

Question

Quizplus · Accepted Answer

Nervonic acid has 24 carbons and one double bond at the 15th carbon. Looking at the reaction sequence, the starting material is palmitic acid (16 carbons) which undergoes elongation to form stearic acid (18 carbons), then further elongation to form oleic acid (18 carbons, one double bond at 9th carbon), followed by further elongation to form erucic acid (22 carbons, one double bond at 13th carbon), and finally elongation to form nervonic acid (24 carbons, one double bond at 15th carbon). The only option with 24 carbons and a double bond at the 15th carbon is option B: 11eaa4bc_3e43_82d1_9180_af33f11edc63_TB5902_00.
