The seesaw geometry occurs when a molecule has a steric number of 5, with the central atom being bonded to 4 other atoms and 1 lone pair (AX 4 E 1 in AXE notation). An atom bonded to 5 other atoms (and no lone pairs) forms a trigonal bipyramid with two axial and three equatorial positions, but in the seesaw geometry one of the atoms is replaced ...
For example, from the word ether, referring to an oxygen-containing compound having the general chemical structure R−O−R′, where R and R′ are organic functional groups and O is an oxygen atom, comes the word thioether, which refers to an analogous compound with the general structure R−S−R′, where S is a sulfur atom covalently ...
Like many other sulfur-containing compounds, volatile sulfides have foul odors. [1] A sulfide is similar to an ether except that it contains a sulfur atom in place of the oxygen. The grouping of oxygen and sulfur in the periodic table suggests that the chemical properties of ethers and sulfides are somewhat similar, though the extent to which ...
The related compound FSSSF 3 has a similar structure, but with an extra sulfur atom in the chain. Thiothionyltetrafluoride, S=SF 4 may exist as a gas. It is less energetically favourable to FSSF 3 by 37 kJ/mol, but has a high energy barrier of 267 kJ/mol. [10] However it may disproportionate rapidly to sulfur and sulfur tetrafluoride. [10]
The S–S distances are equivalent and are 191.70 ± 0.01 pm, and with an angle at the central atom of 117.36° ± 0.006°. [2] However, cyclic S 3 , where the sulfur atoms are arranged in an equilateral triangle with three single bonds (similar to cyclic ozone and cyclopropane ), is calculated to be lower in energy than the bent structure ...
A chart or table of nuclides maps the nuclear, or radioactive, behavior of nuclides, as it distinguishes the isotopes of an element.It contrasts with a periodic table, which only maps their chemical behavior, since isotopes (nuclides that are variants of the same element) do not differ chemically to any significant degree, with the exception of hydrogen.
