In which of the following molecules are all the bonds not equal?
ClF3
BF3
AlF3
NF3
A.
ClF3
In ClF3 all bonds are not equal due to trigonal -bipyramidal (sp3d-hybridisation) geometry of ClF3 molecule.
BF3 and AlF3 show trigonal symmetric structure due to sp2-hybridisation.
NF3 shows pyramidal geometry due to sp3 hybridization.
Name the conditions for the formation of an ionic bond between two atoms.
What is crystal lattice?
What is electrovalency?
What bond is present in MgCl2 molecules?
Two elements A and B have the electronic configuration as:
A = 1s22s22p63s2 and B = 1s22s22p5
Write the empirical formula of the substance containing A and B.
What type of bonding would you expect between:
(i) a metal and a non-metal
(ii) a non-metal and another non-metal?
Give reasons in one or two sentences for the observation that in their compounds non-metals form anions and not cations.
