Both B and C are non-metals and therefore, bond formed between them will be covalent.

Just check the electronegativity difference between the elements. if it is more than 1.9 than ionic otherwise covalent bond forms. or draw the possible lewis structure and analyse.

The bond between B and C will be Covalent.

Covalent bonding occurs when two atoms share electrons in order to achieve a stable electron configuration. In this type of bond, the electrons are not transferred from one atom to another, but rather shared between the atoms involved.

Explanation:

1. Covalent Bonding:
Covalent bonding occurs between two nonmetal atoms or a nonmetal and a metalloid. These atoms have high electronegativity values and tend to attract electrons more strongly. As a result, they share electrons to achieve a stable electron configuration.

2. Electronegativity Difference:
To determine the type of bond, we need to consider the electronegativity difference between the two atoms. Electronegativity is the ability of an atom to attract electrons towards itself. In a covalent bond, the electronegativity difference between the two atoms is typically small.

3. Electronegativity of B and C:
Since the question does not provide specific information about the atoms B and C, we can assume that B and C are both nonmetals or a nonmetal and a metalloid. In such cases, the bond between them is mostly covalent.

4. Ionic Bonding:
Ionic bonding occurs when there is a large electronegativity difference between the atoms involved. In an ionic bond, one atom completely transfers electrons to another atom. This results in the formation of positive and negative ions, which are attracted to each other due to electrostatic forces.

5. Hydrogen Bonding:
Hydrogen bonding is a special type of dipole-dipole interaction that occurs between a hydrogen atom bonded to a highly electronegative atom (such as nitrogen, oxygen, or fluorine) and another electronegative atom in a neighboring molecule. This type of bonding is weaker compared to covalent and ionic bonding.

Conclusion:
Based on the given options, the bond between B and C will be covalent, as it involves the sharing of electrons between the atoms. Ionic bonding requires a large electronegativity difference, which is not specified in the question. Hydrogen bonding involves the presence of a hydrogen atom bonded to a highly electronegative atom, which is not mentioned in the question either. Therefore, covalent bonding is the most appropriate answer.
