The entity integrity rule states that a primary key attribute can be null. Thus the statement is false.
<h3>What is an entity?</h3>
An entity is refer to any object that exists in reality. These entities are Independent in nature. Each row in a table should be a distinct entity, which is ensured by entity integrity.
The entity integrity rule states that a primary key attribute can not be null as it shows unique characteristics of an entity.No primary key value can be null according to the entity integrity constraint because it is needed to identify specific attribute values in relation.
Therefore, the statement is False.

Prediction for the reactivity of a chlorine directly on the double bond of an alkene would be in the following:
A dipole is created in the halogen molecule as the non-polar chlorine molecule approaches the alkene double bond.
A chloride ion is produced when the pi link in the alkene double bond breaks and establishes a bond with the delta positive Cl atom.
The chloride ion undergoes carbocation as a result, and along with the carbocation, a single electron pair forms a dative bond.
Carbon double bonds are more powerful and compact than single bonds. The number of bonds is two.
Additionally, double bonds have a lot of electrons, which could make them more reactive in the presence of a powerful electron acceptor.
