Question:
Given below are two statements:
Statement I: All the pairs of molecules (PbO, PbO₂); (SnO, SnO₂) and (GeO, GeO₂) contain amphoteric oxides.
Statement II: Glycine does not have any chiral carbon.
In the light of the above statements, choose the correct option.

Statement II: Glycine does not have any chiral carbon.
In the light of the above statements, choose the correct option.
Show Hint
GeO is acidic, and only glycine lacks a chiral carbon. Amphoteric oxides can react with both acids and bases.
Updated On: Jan 23, 2026
- Both Statement I and Statement II are correct.
- Both Statement I and Statement II are incorrect.
- Statement I is correct and Statement II is incorrect.
- Statement I is incorrect and Statement II is correct.
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Analyzing the statements.
- Statement I: The molecules PbO, PbO₂; SnO, SnO₂; GeO, GeO₂ do not all contain amphoteric oxides. GeO is distinctly acidic, not amphoteric.
- Statement II: Glycine does not have any chiral carbon. This is true because glycine is the only amino acid that lacks a chiral center.
Step 2: Conclusion.
Statement I is incorrect, and Statement II is correct. Therefore, the correct answer is (4).

- A linear octasaccharide (molar mass = 1024 g mol$^{-1}$) on complete hydrolysis produces three monosaccharides: ribose, 2-deoxyribose and glucose. The amount of 2-deoxyribose formed is 58.26 % (w/w) of the total amount of the monosaccharides produced in the hydrolyzed products. The number of ribose unit(s) present in one molecule of octasaccharide is _____.
Use: Molar mass (in g mol$^{-1}$): ribose = 150, 2-deoxyribose = 134, glucose = 180; Atomic mass (in amu): H = 1, O = 16- JEE Advanced - 2025
