A pnictogen hydride, this colourless, highly toxic gas is the principal covalent hydride of antimony, and a heavy analogue of ammonia. The molecule is pyramidal with H–Sb–H angles of 91.7° and Sb–H distances of 170.7 pm (1.707 … See more SbH3 is generally prepared by the reaction of Sb sources with H− equivalents: 2 Sb2O3 + 3 LiAlH4 → 4 SbH3 + 1.5 Li2O + 1.5 Al2O3 4 SbCl3 + 3 NaBH4 → 4 SbH3 + 3 NaCl + 3 BCl3 Alternatively, … See more As stibine (SbH3) is similar to arsine (AsH3); it is also detected by the Marsh test. This sensitive test detects arsine generated in the … See more The toxicity of stibine is distinct from that of other antimony compounds, but similar to that of arsine. Stibine binds to the haemoglobin of red blood cells, causing them to be … See more The chemical properties of SbH3 resemble those for AsH3. Typical for a heavy hydride (e.g. AsH3, H2Te, SnH4), SbH3 is unstable with respect to its … See more Stibine is used in the semiconductor industry to dope silicon with small quantities of antimony via the process of chemical vapour deposition See more SbH3 is an unstable flammable gas. It is highly toxic, with an LC50 of 100 ppm in mice. See more • Antimony (Sb) • Arsine (AsH3) • Devarda's alloy, also used to produce arsine and stibine in the lab • List of highly toxic gases • Marsh test, first used to analyse AsH3 and SbH3 See more

Solved Of the molecules below, the bond in __________ is the - Chegg

WebThus, all are polar. However, intermolecular interactions for PH3, AsH3, and SbH3 are governed by London or van der Waals’ forces which arise from temporary dipoles created as the electrons in the molecules move around and are occasionally “piled up” in one section of the molecule less so than being in other sections. WebMay 24, 2015 · The answer is (C) have polar covalent bonds with a partial negative charge on the hydrogen atoms. If you only go by the options given, the answer will be obvious because the difference in electronegativity between the two atoms is very small, which eliminates the possibility of their bond having a predominat ionic character.
