MHT CET · Chemistry · Some Basic Concepts of Chemistry
Identify number of moles of donor atoms in \(2 \mathrm{n}\) mole of \(\mathrm{SCN}^{-}\).
- A 3n
- B 6n
- C 4n
- D n
Answer & Solution
Correct Answer
(C) 4n
Step-by-step Solution
Detailed explanation
\(\mathrm{SCN}^{-}\)has two donor atoms nitrogen and sulfur either of which links to metal atom/ion when in forms a coordinate bond. Therefore, 1 mole of \(\mathrm{SCN}^{-}\)will have 2 moles of donor atoms.
Hence, \(2 \mathrm{n}\) moles of \(\mathrm{SCN}^{-}\)will have \(4 \mathrm{n}\) moles of donor atoms.
Hence, \(2 \mathrm{n}\) moles of \(\mathrm{SCN}^{-}\)will have \(4 \mathrm{n}\) moles of donor atoms.
