What are condition for geometrical isomerism in coordination compounds?
Among all type of geometries in coordination compounds, only squar planer , octahedral and dodecahedral will show geometrical isomerism. The necessary and sufficient conditions is for every position of ligands there must be at least one "CIS" (separated by 90°) and one must be "TRANS" (seperated by 180°).
What is the temperature at density of water is maximum ?
The maximum density of water is an exceptionally give a irregular trends, which reaches a density peak at 3.98 °C ~ 4.00℃ or (39.16 °F).
Arrange the silicon halides into decreasing order of Lewis acids Character? SiF3, SiCl3, SiBr3, SiI3
In case of silicone halides inductive effect dominate over back bonding hence lewis acid character decided by inductive effect.
Hence order of lewis acid character SiF3 >SiCl3 > SiBr3 > SiI3
