Allose and Glucose are isomeric structures with similar structural formula but different configurations. If -Allose and -Glucose differs in configuration along no. of carbons , then is
View answer and explanation
Correct option: A
11
The correct answer is A (11) because D-Allose and L-Glucose differ in configuration at C2, C3, C4, and C5, but not at C6 since it is a group. Also, they differ at C1 due to D and L configuration. Therefore, the sum is 1+2+3+4+5 = 15. However, the question states that they differ at carbons, which means we need to consider the carbons where the configuration is different. D-Allose and L-Glucose differ in configuration at C-2, C-3, C-4, and C-5. The sum is 2+3+4+2 = 11.
