Three cyclic structures of monosaccharides are given below which of these are anomers.
(i) I and II
(ii) II and III
(iii) I and III
(iv) III is anomer of I and II
The answer is the option (i). Anomers are the compounds are the cyclic structures of monosaccharides which differ at the carbon-1 in their structure. So, option (i) I and II is the right answer.
Monosaccharides are the simplest carbohydrates, made up of carbon, hydrogen, and oxygen atoms. They are the basic unit of carbohydrates and cannot be broken down further. The general formula for monosaccharides is (CH2O)n, where n is a number greater than or equal to 3.
