Nitrogen forms stable N2 molecule, but phosphorus is converted to P4 from P2 because
bonding is strong in phosphorus
bonding is weak in phosphorus
double bond is present in phosphorus
single P-P bond is weaker than N-N bond
An aqueous solution of titanium chloride, when subjected to magnetic measurement, show zero magnetic moment. The formula of complex in aqueous solution is
[Ti(H2O)6]Cl4
[Ti(H2O)6]Cl3
[Ti(H2O)5Cl]Cl2
[Ti(H2O)6]Cl
A.
[Ti(H2O)6]Cl4
The formula of complex in aqueous solution is [Ti(H2O)6]Cl. Since, dipole moment is equal to zero. It means titanium is present as Ti4+ ion, as it has no unpaired electron.
Ti22 = [Ar] 3d24s2; Ti4+ = [Ar]3sd04s0
