Key Differences
In a Covalent Bond, the electrons are usually shared equally or nearly equally between two atoms, making their bond stable. In contrast, in a Dative Bond, since one atom donates both shared electrons, the bond arises due to the desire of one atom to donate an electron pair and another atom to accept it.

The key distinction between the Covalent Bond and the Dative Bond lies in the origin of the electrons being shared. For a standard covalent bond, each atom contributes one electron. For a dative bond, one atom is the sole provider of the two shared electrons.

While every Dative Bond can be described as a covalent bond, not every Covalent Bond can be described as dative. This is because dative bonding is a specific scenario of electron sharing, while covalent bonding is a broader category.

Molecules that contain Covalent Bonds can have atoms with similar or different electronegativities. However, in molecules with a Dative Bond, the bond is often between a Lewis base (electron pair donor) and a Lewis acid (electron pair acceptor).

A Covalent Bond is a type of chemical bond where atoms come together by sharing electrons, allowing them to fill their outermost shell. A Dative Bond, also known as a coordinate bond, is a specialized type of covalent bond where one atom provides both the electrons for sharing.
