Question

A)

The correct name for the complex ion [Cr(H 20) 4Cl 2] + is a. tetraaquadichlorochromium. O b. tetraaquadichlorochromate(III). Oc. tetraaquadichlorochromium(III). O d. dichlorotetraaquochromium(II). e. tetraaquadichlorochromium(II).

B)

C)

D)

E)

Answer 1

A) [cat (940), ] If there ip positive charge is complex ([]). ethen metal (central atom) end with its actual nome. It there in negative charge then it ends with ate. tetraaque dichloro chromium (m) ® [morem complex has negative charge and with ate hera eyono molybdenate (1) . [Conny a atom in charge of complex ion = +1 No of atom connected with central complex - 6 20 + 4H₂) Onidation state of co=+3 a [+1, +3,6)

(0) [co (NH3) ] [ NiCONS] Coordination of Ni = atom briked with Ni in complex = 5 (E) na Na, [Ni(cals] Costination of Ni = Atom linked with Ni si complex

if the solution helps then rate it.
