Real questions that test this

खालीलपैकी कोणता पर्याय संयुगे 'A' आणि 'B' च्या बाबतीत अचूक आहे ? A = CH2OH-C(=O)-(HO-C-H)_3-CH2OH, B = H-C(=O)-(HO-C-H)_4-CH2OH / Which of the following option is correct about compounds A and B ? A = CH2OH-C(=O)-(HO-C-H)_3-CH2OH, B = H-C(=O)-(HO-C-H)_4-CH2OH

1)A आणि B ही फक्त एकमेकांची प्रतिबिंबिरूपिते आहेत / A and B are only optical isomers of each other
2)A आणि B ही फक्त एकमेकांची क्रियात्मक गट समसूत्री आहेत / A and B are only functional isomers of each other✓ Correct
3)A आणि B ही एकमेकांची प्रतिबिंबिरूपिते आणि क्रियात्मक गट समसूत्री आहेत / A and B are optical as well as functional isomers of each other
4)A आणि B ही ऐकमेकांची प्रतिबिंबिरूपिते नाही आणि क्रियात्मक गट समसूत्री नाहीत / A and B are neither optical nor functional isomers of each other

Compound A is a ketohexose (contains a ketone group) and Compound B is an aldohexose (contains an aldehyde group). Since they have the same molecular formula but different functional groups, they are functional isomers.
