Concept explainers
Interpretation: The lines representing a hydrogen bond needs to be explained.
Concept introduction: The hydrogen bond may be defined as a strong dipole-dipole forces of attraction that operates between a hydrogen atom that is covalently bonded to an atom of high electronegativity.
Answer to Problem 3STP
Option “A” is correct.
Explanation of Solution
The covalent bond between a hydrogen and an electronegative element is considerably polar because the electronegative atom attracts the bonding electron towards itself. The partial positive charge on hydrogen attracts the partial negative charge of a second electronegative atom forming what is called hydrogen bonding. In hydrogen bonding, dotted lines represent a force of attraction between two dipoles not a permanent bond between hydrogen of one molecule with oxygen of different molecule.
A solid line represents a permanent bond (either ionic or covalent) within the molecule Hence B, C, and D cannot be the answer.
