Question

a chemical bond formed when two atoms share electrons
choose an answer
1 hydrophobic bond
2 polar bond
3 covalent bond
4 hydrogen bond

Explanation:

A covalent bond is defined as a chemical bond formed when two atoms share electrons. A polar bond is a type of covalent bond where there is an unequal sharing of electrons due to differences in electronegativity between the atoms. A hydrophobic bond is related to the interaction of non - polar substances in a polar environment (like water). A hydrogen bond is an intermolecular force between a hydrogen atom (covalently bonded to a highly electronegative atom like O, N, or F) and another electronegative atom. Since the question is about a bond formed by electron - sharing (the general definition of a covalent bond, with polar bond being a specific type of covalent bond), and the most general answer among the options for electron - sharing is covalent bond.

Answer:

1. Covalent Bond
