JEE Advanced levelSingle correct optionDifficulty 3 of 3pn090
Consider the statements: (i) Rhombic sulphur is insoluble in water but dissolves in CSX2. (ii) Monoclinic sulphur is the stable form above 369 K. (iii) Sulphur vapour at about 1000 K consists mainly of paramagnetic SX2 molecules. (iv) The SX8 ring is planar. The number of correct statements is
A2
B3
C1
D4
Answer: B
Statements (i), (ii) and (iii) are standard facts (SX2 is paramagnetic like OX2). The SX8 ring is puckered (crown), so (iv) is wrong. Hence 3 are correct.
