Explain why Mo(PMe3)5H2 is a dihydride (contains two separate H ligands), but Mo(CO)3(PR3)2(H2) contains the dihydrogen ligand (Me = methyl, R = isopropyl).
Dihydrogen complex has more sigma donor character than hydride complex. For the first compound PMe3 have no proper pi-acceptor ability. So, the compound is hydride but due to presence of CO,...

Write Write a SQL query to retrieve the unique # of molecules from a table named 'reactants' in a database named 'reactions'. The molecules are represented as SMILES in the column named 'SMILES
The SMILES format is a linear text format which can describe the connectivity and chirality of a molecule. Canonical SMILES gives a single 'canonical' form for any particular molecule. See...

Are Group 3A elements more reactive than 4A?
Is Fe Zn Cu more reactive
How can you tell by looking at the periodic table?
There are two main characteristics determining the chemical reactivity: ionization energy for metals and electronegativity for non-metals. Ionization energy is increasing from left to right in a period and decreasing...

the vapor pressures of pure propyl alcohol and isopropyl alcohol are 21.0 mmHg and 45.2 mmHg. respectively, above a solution in which the mole fraction of isopropyl alcohol is 0.750
Pressure is directly proportional to MoleTherefore,P = knk= P/nP1/n1 = P2/n221.0 mmHg / x = 45.2 mmHg/0.750x = (21.0 mmHg * 0.750) / 45.2 mmHgx= 0.35 (pure propyl alcohol mole ratio)
