Beryllium fluoride has distinctive optical properties. In the form of fluoroberyllate glass, it has the lowest refractive index for a solid at room temperature of 1.275. Its dispersive power is the lowest for a solid at 0.0093, and the nonlinear coefficient is also the lowest at 2 × 10 −14.
When comparing a polar and nonpolar molecule with similar molar masses, the polar molecule in general has a higher boiling point, because the dipole–dipole interaction between polar molecules results in stronger intermolecular attractions. One common form of polar interaction is the hydrogen bond, which is also
Structure of beryllium fluoride (BeF 2), a compound with a linear geometry at the beryllium atom.. The linear molecular geometry describes the geometry around a central atom bonded to two other atoms (or ligands) placed at a bond angle of 180°.
The geometry of a molecule of BF 3 is trigonal planar.Its D 3h symmetry conforms with the prediction of VSEPR theory.The molecule has no dipole moment by virtue of its high symmetry.
The conductivity is due to that the main carbon chain separates from the side chains, thus forming polar and non-polar regions. This form is also very hydroscopic. [132] Fluoroelastomers, like other elastomers (artificial rubbers), consist of disordered polymer chains connected in three dimensions.
Tetrafluoroberyllate or orthofluoroberyllate is an anion with the chemical formula [Be F 4] 2−.It contains beryllium and fluorine.This fluoroanion has a tetrahedral shape, with the four fluorine atoms surrounding a central beryllium atom.
Beryllium hydride (systematically named poly[beryllane(2)] and beryllium dihydride) is an inorganic compound with the chemical formula (BeH 2) n (also written ([BeH 2]) n or BeH 2).
Lithium fluoride is an inorganic compound with the chemical formula LiF. It is a colorless solid that transitions to white with decreasing crystal size. Its structure is analogous to that of sodium chloride, but it is much less soluble in water.
