Ethelene+diaminotetraacetate---->1,4- diaminobutane from ethylene CH 2 =CH 2 +EDTA---->NH 2 -CH 2 -CH 2 -CH 2 -CH 2 -NH 2
Silicon has 4 electrons in the outermost orbit. In forming the bonds: (1) It gains electrons (2) It loses electrons (3) It shares electrons (4) None of these Ans: I
Given that ?H°298 for the reaction is -92.2 kJ mol-1, which is larger, the total bond dissociation energy of the reactants or the total bond dissociation energy of the products?
The number of unpaired electrons in Fe 3+ (Z= 26) are: (1) 5 (2) 6 (3) 3 (4) 4 Ans: 5
Why is the total energy of a many-electron atom not equivalent to the sum of the orbital energies for every electron?
Why can classical (Werner) octaedral complexes with no pi-bonding have between 12-22 valence electrons, whereas octahedral complexes with pi-bonding must have 18 electrons?
