QUESTION: 6

According to molecular orbital theory which of the following statement about the magnetic character and bond order is correct regarding O2+               [JEE 2004]

Solution:

QUESTION: 7

Which species has the maximum number of lone pair of electrons on the central atom ? [JEE 2005]

Solution:
QUESTION: 8

The percentage of p-character is the orbitals forming P_P bonds in P4 is [JEE 2007]

Solution: Hybridisation around P is sp3 (1 lone pair , 3 sigma bond ) so P character is (3×100/4) 75%.
QUESTION: 9

Among the following, the paramagnetic compound is                         [JEE 2007]

Solution: KO2 is a superoxide in which, only one electron is released from the dioxygen atom and a superoxide ion is represented as 02 . So, in KO2 the oxygen atoms bear -1/2 oxidation state and they also behave as a free radical species, having an unpaired electron. We know that a molecule becomes paramagnetic due to the presence of unpaired electrons. Hence, KO2 behaves as paramagnetic molecule.
QUESTION: 10

The species having bond order different from that in CO is                       [JEE 2007]

Solution:
QUESTION: 11

The structure of XeO3 is                            [JEE 2007]

Solution:
QUESTION: 12
