The number of π molecular orbitals in a molecule is always equal to the number of p orbitals used to construct the π bonds.
An electron's position and wave-like behavior within a molecule are described by a mathematical function called a molecular orbital. Chemical, as well as physical properties like the probability of locating an electron in a particular area, can be determined using this function.
A molecular orbital would be created when two atomic orbitals cross one other along the internuclear axis. A molecular orbital is created when two atomic orbitals cross each other sideways.
Therefore, the number of π molecular orbitals in a molecule is always equal to the number of p orbitals used to construct the π bonds.
Hence, the correct answer will be option (a).

Explanation:
An ion is a charged atom or molecule. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
9.5 % ( w /v ) :
9.5 g ------------------- 100 mL ( solution )
33 g -------------------- ( volume )
Volume = 33 . 100 / 9.5
Volume = 3300 / 9.5
Volume = 347.36 mL

Answer:
0.112 M.
Explanation:
- Molarity is the no. of moles of solute in a 1.0 L of the solution.
M = n/V.
<em>M = (mass/molar mass)solute x (1000/V of the solution).</em>
mass = 127.62 g.
molar mass = 286.138 g/mol.
V of the solution = 4.0 L = 4000.0 mL.
<em>∴ M = (mass/molar mass)solute x (1000/V of the solution)</em> = (127.62 g / 286.138 g/mol) x (1000 / 4000.0 mL) = <em>0.1115 M ≅ 0.112 M.</em>
