(a)
Interpretation:
Whether
Concept Introduction:
The bond formed between the hydrogen atom attached to electronegative atom and other electronegative atoms such as fluorine, oxygen, and nitrogen is termed as hydrogen bond. It occurs in polar molecules that have dipole-dipole interaction. It is denoted by dotted line.
