- C\(_6\)H\(_{12}\)O\(_6\)
- C\(_5\)H\(_{12}\)O\(_5\)
- C\(_2\)H\(_4\)O\(_2\)
- C\(_5\)H\(_{10}\)O\(_5\)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Identify carbohydrate type.
Rhamnose is a deoxy sugar, meaning it has one oxygen atom less than typical hexoses/pentoses. It is a methyl pentose sugar.
Step 2: Recall general formula trend.
Monosaccharides generally follow: \[ C_nH_{2n}O_n \] But deoxy sugars deviate due to loss of oxygen atom.
Step 3: Apply structural knowledge.
Rhamnose is a 6-deoxy-hexose or methyl pentose derivative, giving formula: \[ C_5H_{12}O_5 \]
Step 4: Eliminate incorrect options.
C\(_6\)H\(_{12}\)O\(_6\) is glucose (not rhamnose) C\(_5\)H\(_{10}\)O\(_5\) is ribose Others do not match deoxy structure
Step 5: Final conclusion.
\[ \boxed{C_5H_{12}O_5} \]
