What fraction of one edge centred octahedral void lies in one unit cell of fcc?
<!-- [if !supportLineBreakNewLine]-->
<!--[endif]-->
One edge of an cube is common to four unit cells. Hence One edge centre OV contribute 1/4 to one unit cell.

Amongst the given options, which of the following molecules/ion acts as a Lewis acid?
<!-- [if !supportLineBreakNewLine]-->
<!--[endif]-->
BF? behaves as Lewis acid due to incomplete octet in valence shell of Boron. Hence it can accept a lone pair of electrons.

Which of the following molecules is non-polar in nature?
sp³d Dipole moment (μ) = 0
Trigonal bipyramidal Non-polar
Upvote The order of energy absorbed which is responsible for the color of complexes.
(A) [Ni(H₂O)₂(en)₂]²⁺
(B) [Ni(H₂O)₄(en)]²⁺
(C) [Ni(en)₃]²⁺
The order of energy absorbed which is responsible for the color of complexes.
(A) [Ni(H₂O)₂(en)₂]²⁺
(B) [Ni(H₂O)₄(en)]²⁺
(C) [Ni(en)₃]²⁺
More the number of strong field ligands in a complex greater the energy absorbed by a complex.
Upvote The IUPAC name of the complex - [Ag(H₂O)₂[Ag(CN)₂] is:
The IUPAC name of the complex - [Ag(H₂O)₂[Ag(CN)₂] is:
[Ag (H? O)? ]? [Ag (CN)? ]? is called diaquasilver (I)dicyanidoargentate (I).
Upvote The nature of bonding in Ni (CO)? includes synergic bonding. The synergic bonding in metal carbonyls like nickel tetracarbonyl is due to two-way interaction of metal and carbonyl ligand electron density donation.
The synergic bonding is best explained thorugh Molecular Orbital Theory (MOT), which ex
Upvote The metal-carbon bonds (M-C) in metal carbonyls are due to the synergic interaction between the metal and carbonyl group. There are two types of bonding between metal and carbonyl group.
? -bond in Metal Carbonyls: The Carbonyl (CO) ligand donates a lone pair of electrons to the metal center to
