• A. of same constitution at $C -1$
• B. of same constitution at $C-2$
• C. of same constitution & same configuration at $C$ $3, C-4, C-5 \& C-6$ but different constitution $\&$ configuration at $C-1, \& C-2$ which become identical by osazone formation
• D. All of these

Answer 1

Answer: (C)

Correct answer is (c) of same constitution & same configuration at $C$ $3, C-4, C-5 \& C-6$ but different constitution $\&$ configuration at $C-1, \& C-2$ which become identical by osazone formation
