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:

  1. A Statement \(I\) is false but Statement \(II\) is true.
  2. B Both Statement \(I\) and Statement \(II\) are true.
  3. C Both Statement \(I\) is true but Statement \(II\) is 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.
