The possible diastereoisomers for given complex [ C r ( C 2 O 4 ) 2 ( H 2 O ) 2 ] − should be drawn and the one that exist as pair of enantiomers should be identified. Concept Introduction: Isomerism: Two chemical compounds are said to be isomers if they have same number and kind of atoms but different only in their orientation that is structural arrangements. There are different types of isomerism in which geometric is of one type where the rotation around the atom is restricted like in cis-trans configuration. This is also refereed as cis-trans isomerism. Structural isomers: Have same molecular formula but different bonding arrangements of atoms. It is classified into coordination isomer (occurs by exchanging a coordinated ligand and the counter-ions) and linkage isomers (ligand attached through different atoms to the metal). Stereoisomers: differ in their spatial arrangement of atoms. Diastereoisomers: The stereo isomers of one compound which are not mirror images with each other are referred as diastereoisomers.

An open vessel containing water stands in a laboratory measuring 5.0 m x 5.0 m x 3.0 m at 25 °C ; the vapor pressure (vp) of water at this temperature is 3.2 kPa. When the system has come to equilibrium, what mass of water will be found in the air if there is no ventilation? Repeat the calculation for open vessels containing benzene (vp = 13.1 kPa) and mercury (vp = 0.23 Pa)
