Question

$I$. Hydrogen bonds are a specific type of dipole-dipole interaction.
$II$. When hydrogen atoms are bonded to highly electronegative elements such as nitrogen, oxygen or fluorine electrons are shared unevenly between the hydrogen and the other atom.

• A. Statement $I$ is true, Statement $II$ is true and is a correct explanation of the phenomena described in $I$
• B. Statement $I$ is true, Statement $II$ is false
• C. Statement $I$ is false, Statement $II$ is true
• D. Statement $I$ is false, Statement $II$ is false

Answer 1

Answer: (A)

Statement $I$ is true, Statement $II$ is true and is a correct explanation of the phenomena described in $I$

Hydrogen bonds are specific type of dipole dipole interactions because hydrogen bonds are formed between H and an electronegative atom, this dipole is created due to this electronegative atom and the shared electrons are unevenly distributed between the H and the other atom.
