Which of the following formula correctly represents the double salt "Carnallite"?

If the concentration of a reactant is reduced to half, the rate of reaction becomes \(\frac{1}{4}\). What will be the order of reaction?

Primary Alkyl halide \(C _4 H _9 Br (X)\) reacts with alcoholic KOH to give the compound \((Y)\). Compound \((Y)\) is reacted with HBr to give \((Z)\) which is an isomer of \((X)\). When \((X)\) is reacted with \(Na /\) dry ether, it gives a compound \((T), C _8 H _{18}\), which is different from the compound formed when \(n\)-butyl bromide is reacted with \(Na /\) dry ether. The correct IUPAC name of (T) is:

Deficiency disease caused due to deficiency of Vitamin \(K\) is :

Werner was the first to describe the bonding features in coordination compounds. But his theory could not answer basic questions like :
(i) Why only certain elements possess the remarkable property of forming coordination compounds ?
(ii) Why the bonds in coordination compounds have directional properties ?
(iii) Why coordination compounds have characteristics magnetic and optical properties ?
Many approaches have been put forth to explain the nature of bonding in coordination compounds vix. Valence Bond Theory (VBT), Crystal Field Theory (CFT), Ligand Field Theory (LFT) and Molecular Orbital Theory (MOT).
We shall focus our attention on elementary treatment of the application of VBT and CFT to coordination compounds.
According to this theory, the metal atom or ion under the influence of ligands can use its ( \(n -1\) )d, ns np or ns, np, nd orbitals for hybridisation to yield a set of equivalent orbitals of definite geometry such as octahedral, tetrahedral, square planar and so on.
These hybridised orbitals are allowed to overlap with ligand orbitals that can donate electron pairs for bonding.
Predict the type of hybridisation state in \(\left[ CoF _6\right]^{3-}\)
