Question

Which statement accurately describes the allotropes of Tin mentioned in the document?
Options
A Tin has two allotropes: white tin (non-metallic) and grey tin (metallic).
B White tin is metallic and can transform into non-metallic grey tin upon heating.
C Grey tin is non-metallic and can transform into metallic white tin upon heating.
Correct Answer
D Tin has only one metallic allotrope.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 13 shows a diagram indicating 'White tin (Metallic)' transforms to 'Grey tin (non metallic)' in the 'cold' and the reverse reaction ('Grey tin (non metallic)' to 'White tin (Metallic)') happens with 'heat'. This means grey tin (non-metallic) transforms to white tin (metallic) upon heating.

Hint

Pay close attention to the conditions (cold/heat) and the metallic/non-metallic nature of the tin allotropes in the diagram.
