Question

Regarding the structure of $S O_{2}$ and $S e O_{2}$ which of the following is true -

• A. The gaseous $S O_{2}$ and $S e O_{2}$ have same $V$ -shaped molecule both in solid and gas phase
• B. At room temperature both $S O_{2}$ and $S e O_{2}$ are solids.
• C. In the solid phase the structure of $S O_{2}$ is $V$ -shaped discrete molecule but $S e O_{2}$ is cyclic trimeric
• D. In solid phase the structure of $S O_{2}$ is $V$ -shaped discrete molecule but $S e O_{2}$ has linear polymeric chain

Answer 1

Answer: (D)

The gaseous $S O_{2}$ and solid $S O_{2}$ both are V-shaped discrete molecule. $S e O_{2}$ is solid at room temperature and solid $S e O_{2}$ is polymerised by infinite chain.
