An element ' X ' with the atomic number 13 forms a complex of the type [ XCl ( H ₂ O )₅ ]²⁺ . The covalency and oxidation state of X in it are respectively

Options

  1. A5,+2
  2. B6,+2
  3. C5,+3
  4. D6,+3

Correct answer

D. 6,+3

Step-by-step solution

Element ' X ' is forming a complex of the type [X Cl ( H ₂ O )₅ ]²⁺ . Total number of ligands attached to X is 6 (one Cl and five H ₂ O ). Cl is a unidentate ligand with charge -1 . H ₂ O is a unidentate ligand with charge 0. x+(-1)+0=+2x-1=+2x=+2+1=+3 Oxidation state of x is +3 .
