Toluene does not undergo reaction with bromine water due to aromatic stabilization.
<h3>What is addition reaction?</h3>
The term addition reaction refers to a type of reaction in which atoms or groups are added across the double bond. This type of reaction is common to alkenes and alkynes. By this reaction, unsaturated compounds are reduced to their saturated monologues.
We know that due to aromatic stabilization, compounds that contain the aromatic sextet do not undergo addition reaction such as the addition of bromine. Rather, what occurs in such systems is a substitution reaction under appropriate conditions.
It then follows that toluene does not undergo reaction with bromine water due to aromatic stabilization.

Answer:
d. In a stable molecule having an even number of electrons, all electrons must be paired.
Explanation:
<em>Which of the following statements relating to molecular orbital (MO) theory is incorrect?</em>
<em>a. Combination of two 2p orbitals may result in either σ or π MOs.</em> TRUE. If the atomic orbitals overlap frontally, a σ MO is produced while if the atomic orbitals overlap laterally, a π MO is produced.
<em>b. Combination of two atomic orbitals produces one bonding and one antibonding MO.</em> TRUE. The bonding MO has less energy than the antibonding MO.
<em>c. A bonding MO is lower in energy than the two atomic orbitals from which it is formed.</em> TRUE. The bonding MO is more stable than the individual atomic orbitals.
<em>d. In a stable molecule having an even number of electrons, all electrons must be paired.</em> FALSE. Let's consider, for example, the molecular orbitals of O₂:
The electrons in the degenerated π* orbitals are not paired.
<em>e. A species with a bond order of zero will not be stable.</em> TRUE. For a species to be stable, the bond order must be higher than zero.
