Structure of Atom question

2000 · Q107

NEETChemistryStructure of AtomMCQ+4 / −1
Isoelectronic species are
  1. A
    CO, CN−-−, NO+, C22−{_2^{2 - }}22−​
  2. B
    CO−-−, CN, NO,
  3. C
    C2−C_2^ -C2−​
  4. D
    CO, CN, NO, C2

Correct answer: A

No. of electrons CO = CN- = NO+ = C22−C_2^{2 - }C22−​ = 14, So these are isoelectronics.
