Choose the correct answer from the options given below:
The correct increasing order of bond angle among $$F_{2}O, Cl_{2}O$$ and $$Br_{2}O$$ is (X - O - X, where X is F, CI, Br)
In the reation
$$MnO_4^- + 16H^{+} + 10Br^{-} \rightarrow 2Mn^{2+} + 8H_{2}O + 5Br_{2}$$
$$Br^{-}$$ion is the
For the Lanthanides
A. Lanthanides display only the (+3) oxidation state.
B. Oxidation numbers (+2) and (+4) occur when they lead to a noble gas configuration.
C. Oxidation numbers (+2) and (+4) are observed when they lead to a half-filled orbital.
D. $$Yb^{2+}$$ has a completely filled f-orbital
Choose the correct answer from the option given below:
Given below are two statement:
Statement I: The electronic structures of the atoms in the second and third rows of transition metals always follow the pattern of the first row.
Statement II: The electronic configuration of Pd is [Kr] $$4d^{10}$$ $$5s^0$$
In the light of the above statements, choose the correct answer from the options given below:
$$Fe(H_{2}O)_6^{2+}$$ is a high-spin complex that absorbs light at about 1000 nm, corresponding to a transition between $$^5T_{2g}$$ and $$^5E_{g}$$ levels. The wave numbers of the radiation is
The observed magnetic moment of a complex is 1.73 BM. The number of unpaired electrons in the complex is
Given below are two statements : one is labelled as Assertion A and other is labelled as Reason R:
Assertion A : The binding energy of metallic lithium exceeds that of the $$Li_{2}$$ molecule through the Li-Li distance in the metal (3.03) is significantly larger than in the diatomic $$Li_{2}$$ molecule (2.67 A).
Reason R : The bonds in the metal are weaker, but there are more Li-Li bonds in the metal.
In the light of the above statements, choose the correct answer from the options given below:
