Question

4. Calculate theoretical percent of composition of all elements in bis(acetyleacetonate)nickel.dihydrate 5. Additional work: a. What is the coordination number? b. Draw the structure of (i) square planner (ii) tetrahedral and (iii) octahedral con with one example for each.

Answer 1

4. bis (aceta bis (acetyle acetonerte.) nikel. dinyetoate. -H 1.2H₂O in CH3 om From above structure : a) Total Number of carbons = 10 b) Total Number of Ongogens = 4+2 = 6 Total number of Hydrogens = 18 Total Number of. Nickel = 1 And total molas mass of abore complex in 1 Co Hip Oo ni -10x12 +18X1 + 6x16 +59) g/mol = (120 + 18 + 96 +59) almol = 293 g/mol And Percent composition) = 1. - Mass of element Total mass of the complen Ö % composition i0 X 12 4X100 y. 293 og of' Carbon (C) = 40.950/ element

293 6). Y composition of onggen (0)= _ 6X16 - X100 y: = 32.76% C) me comportion of Hystojen (H) = 18,21004 = ? and cer) P. composition of Nickel (16) = 52 x100y = 20.137 5) (a). Answer Coordination number is the number of atoms or ligands attached to a metal centre. for example → Nicco), has coordination number of 4 , since 4 co ligands are attached to Mi (b).
