Question

weak attraction between a hydrogen atom and another atom
choose an answer
1 polar covalent bon
2 peptide bond
3 hydrogen bond
4 ionic bond

Explanation:

A hydrogen bond is a weak attraction between a hydrogen atom (covalently bonded to a highly electronegative atom like oxygen or nitrogen) and another electronegative atom. Polar covalent bonds involve unequal sharing of electrons between atoms. A peptide bond is a covalent bond in proteins. An ionic bond is a strong electrostatic attraction between ions. The description "weak attraction between a hydrogen atom and another atom" directly matches the definition of a hydrogen bond.

Answer:

1. Hydrogen Bond
