Given below are two statements: Statement\(-I\) \(: \alpha\) and \(\beta\) forms of sulphur can change reversibly between themselves with slow heating or slow cooling. Statement\(-II :\) At room temperature the stable crystalline form of sulphur is monoclinic sulphur. In the light of the above statements, choose the correct answer from the options given below:
- A Statement \(I\) is false but Statement \(II\) is true.
- B Both Statement \(I\) and Statement \(II\) are true.
- C Both Statement \(I\) is true but Statement \(II\) is false.
- D Both Statement \(I\) and Statement \(II\) are false.
Answer & Solution
Correct Answer
(C) Both Statement \(I\) is true but Statement \(II\) is false.
Step-by-step Solution
Detailed explanation
\(\alpha-\) sulphur \(\underset{{ < \,369\,K}}{\overset{{ > \,369\,K}}{\longleftrightarrow}}\) \(\beta-\) sulphur at room temperature \(\alpha-\) sulphur (Rhombic) is most stable form.
