Assertion : B2 molecule is diamagnetic.
Reason : The highest occupied molecular orbital is of σ type.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
The statement true for is
it has a non-linear structure
it is called pseudohalogen
the formal oxidation state of nitrogen in this anion is -1
it is isoelectronic with NO2
Which of the following molecule has highest bond energy ?
F-F
N-N
C-C
O-O
C.
C-C
The bond energies of F-F , C - C , N - N and O-O bonds are 33, 80, 39 and 34.2 kJ/mol respectively. Therefore molecule of C-C has the highest bond energy.
Which of the following are arranged in the decreasing order of dipole moment?
CH3Cl, CH3Br, CH3F
CH3Br, CH3Cl, CH3F
CH3Cl, CH3Br, CH3F
CH3Br, CH3F, CH3Cl
