Hydrogen and Fluorine Molecular Compound Formation
Hydrogen (Hydrogen) and Fluorine (Fluorine), Can They Form Molecular Compounds? To understand this, we should investigate its properties.
Hydrogen has an atomic number of one and only one electron in the outer layer. To obtain an electron to achieve a stable structure, it is often positive monovalent and has a certain degree of reduction. For fluorine, the atomic number is nine and the outer layer has seven electrons. Its electronegativity is extremely strong. In order to obtain an electron to reach the octet stable structure, it is often negative monovalent and has strong oxidizing properties.
When the two meet, the electrons of hydrogen tend to shift towards fluorine. Because fluorine attracts electrons very strongly, hydrogen and fluorine combine with a shared electron pair to form a covalent bond, so it is a molecular compound. This compound is hydrogen fluoride (Hydrogen Fluoride, $HF $).
In hydrogen fluoride, hydrogen and fluorine are connected by polar covalent bonds. Due to the difference in electronegativity, one end of fluorine is negatively charged, and the other end of hydrogen is positively charged. Under normal conditions, hydrogen fluoride is a colorless and pungent gas. Due to the existence of hydrogen bonds between molecules, its boiling point is higher than that of ordinary hydrogen halides.
In summary, hydrogen and fluorine can form molecular compounds, which are determined by their atomic structure and chemical properties.
