Question

Consider the following orbitals (i) 3px (ii) 4dz^2 (iii) 3dx^2-y^2 (iv) 3dyz
Then, calculate value of "x + y - z" here x is total number of gerade orbital and y is total number of ungerade orbitals and z is total number of axial orbitals in given above orbitals.

Correct answer: 1

**SOLUTION:**
GERADE ORBITALS (X) = 4DZ^2, 3DX^2-Y^2, 3DYZ (TOTAL = 3)
UNGERADE ORBITALS (Y) = 3PX (TOTAL = 1)
AXIAL ORBITALS (Z) = 3PX, 4DZ^2, 3DX^2-Y^2 (TOTAL = 3)
X + Y - Z = 3 + 1 - 3 = 1.. Step 1: In the hexagonal crystalline structure of ice, each oxygen atom is tetrahedrally coordinated, being covalently bonded to two hydrogen atoms and hydrogen-bonded to two other hydrogen atoms. Step 2: Therefore, each oxygen atom has exactly 2 covalent bonds and 2 hydrogen bonds (not four hydrogen bonds) around it. Step 3: This makes statement (d) incorrect, so (d) is not true about ice.
