D	${\left[Co{F}_6\right]}^{3-}$	IV	$ds{p}^2$

Choose the correct answer from the options given below:

• A. A-IV, B-I, C-III, D-II
• B. A-I. B-IV, C-III, D-II
• C. A-I. B-IV, C-II, D-III
• D. A-IV, B-I, C-II. D-III

Answer 1

Answer: (B)

$Ni(CO{)}_4$ Hybridisation $s{p}^3$
${\left[Ni(CN{)}_4\right]}^{2-}$ Hybridisation $ds{p}^2$
${\left[Co(CN{)}_6\right]}^{3-}$ Hybridisation $d^{2}s{p}^3$
${\left[Co(F{)}_6\right]}^{3-}$ Hybridisation $s{p}^3{d}^2$
