Interpretation: The molecule that can form a hydrogen bond with a water molecule needs to be determined.
Concept Introduction: A hydrogen bond is formed between a molecule having a hydrogen atom covalently bonded with an electronegative atom (hydrogen bond donor) and another electronegative atom having lone pair of electrons (hydrogen bond acceptor).
Answer to Problem 3STP
Option (B)
Explanation of Solution
Reason for correct option:
In a water molecule, a hydrogen atom is covalently bonded with an electronegative oxygen atom. To form a hydrogen atom, the other molecule must have an electronegative atom with lone pair of electrons. In ammonia or
Reason for incorrect option:
In dinitrogen, both the atoms are N thus, there is no electronegativity difference between them. Similarly, there is no electronegativity difference between the atoms of dioxygen.
In methane or
Therefore, options (A), (C), and (D) are incorrect options.
