Question

A coordinate covalent bond is represented by an arrow from donor to acceptor.
(A) TRUE
(B) FALSE

Answer 1

Hint: A covalent bond is sharing of electrons pairs with atoms. These are also known as shared pairs, which are stable as they balance attractive and repulsive forces between atoms. A coordinate covalent bond is also known as dative bond.

Complete step by step solution:
 Coordinate bond is known as the bond formed between the acceptor and the donor atoms. A coordinate covalent bond is also called a dipolar bond. A coordinate bond is shown by an arrow starting from the donor and ending in the acceptor atom.
For example,
 $ R{}_3N \to O $
The arrow represents that the electrons bond starts from $ R{}_3N $ .i.e. amine. In a covalent bond each atom shares one electron. Amine gives one electron to $ O $ atom which is used by the unpaired electrons present on the nitrogen atom forming a covalent bond.
Hence the answer to the question is true; a coordinate covalent bond is represented by an arrow from donor to acceptor.

Additional Information:
 Every arrow used in a chemical equation represents and has a meaning.
For examples,
Forward arrow also known as “reaction arrow”
The resonance arrow
The equilibrium arrow
 The Retrosynthesis Arrow etc

Note:
Covalent bonding also has many interactions; it includes $ \;\sigma - bonding,\; $ $ \;\pi - bonding,\;metal - to - metal{\text{ }}bonding,\;three - center{\text{ }}two - electron{\text{ }}bonds\; $ etc. An example of coordinate covalent bond is seen between molecules of ammonia, which is a lone pair also called as lewis base on the nitrogen atom, and Boron trifluoride (lewis acid having incomplete octet) After, the product formation boron attains complete octet.
