tetrahedral 109.5 degrees

Question 5

which shape is cis and transplatin and bond angle

Answer 5

square planar bond angle 90 degrees

Question 6

what are theligands and the complex in cisplatin

Answer 6

NH3 and Cl with a lone pair for each and platinum metal ion

Question 7

what are the bidentate ligands

Answer 7

1,2-ethanediamine (NH2CH2Ch2NH2)

ethanedioate [OOCCOO]2- with a lone pair on the outside Os

Question 8

which can show optical isomerism

Answer 8

octahedral complexes only when there are three bidentate ligands such as ethanedioate

Question 9

which can show cis trans isomerism

Answer 9

Octahedral - four monodentate of one type and two of another

square planar - when they have two pairs eg Cl and NH3 in cisplatin
