The geometry and the number of unpaired electrons in tetrakis(1-norbomyl)Co, respectively, are:

Step 1: Understand the Coordination of the Metal Center.
The complex is of the form CoL\(_4\), where L represents a norbornyl ligand. The cobalt ion is surrounded by four ligands in a tetrahedral geometry.
Step 2: Analyze the Electron Configuration.
Cobalt in its +2 oxidation state has an electron configuration of [Ar] 3d\(^7\) 4s\(^2\). Since it is surrounded by four ligands, and the complex is tetrahedral, one electron will remain unpaired.
Step 3: Conclusion.
Thus, the geometry is tetrahedral, and there is one unpaired electron.
Final Answer: \[ \text{Tetrahedral and one unpaired electron.} \]

Select the most appropriate option to complete the analogy.
In the given figure, the numbers associated with the rectangle, triangle, and ellipse are 1, 2, and 3, respectively. Which one among the given options is the most appropriate combination of \( P \), \( Q \), and \( R \)?

A regular dodecagon (12-sided regular polygon) is inscribed in a circle of radius \( r \) cm as shown in the figure. The side of the dodecagon is \( d \) cm. All the triangles (numbered 1 to 12 in the figure) are used to form squares of side \( r \) cm, and each numbered triangle is used only once to form a square. The number of squares that can be formed and the number of triangles required to form each square, respectively, are:

The number of patients per shift (X) consulting Dr. Gita in her past 100 shifts is shown in the figure. If the amount she earns is ₹1000(X - 0.2), what is the average amount (in ₹) she has earned per shift in the past 100 shifts?

The Lineweaver-Burk plot for an enzyme obeying the Michaelis-Menten mechanism is given below.

The slope of the line is \(0.36 \times 10^2\) s, and the y-intercept is \(1.20\) mol\(^{-1}\) L s. The value of the Michaelis constant (\(K_M\)) is ________ \( \times 10^{-3} \) mol L\(^{-1}\) (in integer). [Note: \(v\) is the initial rate, and \([S]_0\) is the substrate concentration]
