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
Some of the properties of the two species, are described below. Which one of them is correct?
Dissimilar in hybridisation for the central atom with different structures
Isostructural with same hybridisation for the central atom
Isostructural with different hybridisation for the central atom
Similar in hybridisation for the central atom with different structures
A.
Dissimilar in hybridisation for the central atom with different structures
Thus, in , the central is sp2 hybridised and it has trigonal planar geometry.
Thus, O is sp3 hybridised in H3O+ and H3O+ has pyramidal geometry due to the presence of one lone pair of electrons.
The pairs of species of oxygen and their magnetic behaviours are noted below. Which of the following presents the correct description?
- Both diamagnetic
- Both diamagnetic
- Both diamagnetic
- Both diamagnetic
Dipole moment of HCl = 1.03 D, HI = 0.38 D. Bond length of HCl = 1.3 and HI= 1.6 . The ratio of fraction of electric charge, , existing on each atom in HCl and HI is
12: 1
2.7: 1
3.3: 1
