Sep 26,2020 - Which of the following is the incorrect statement about Zeises salt?a)Zeises salt is diamagneticb)Oxidation state of Pt in Zeiss salt is +2c)All the Pt-Cl bond length in Zeises salt are equald)C-C bond length of ethylene moiety in Zeises salt longer than that of free ethylene moleculeCorrect answer is option 'C'. To better understand why and how ions atoms that have a charge due to the loss or gain of electrons are formed, you can study what happens during the chemical reaction to create salt. The donation is from alkene orbital to vacant metal hybrid orbital. By using our site, you acknowledge that you have read and understand our Cookie Policy, Privacy Policy, and our Terms of Service. (I)overlap of the -electron density of the olefin with a -type acceptor orbital on the metal atom. Can I combine two 12-2 cables to serve a NEMA 10-30 socket for dryer? This decrement occurs only in some selected orbitals which are Advice on teaching abstract algebra and logic to high-school students. And electrons from the filled orbitals of $\ce {Pt}$ is back-donated to the vacant $\pi^*$ orbitals of ethene. Thanks for contributing an answer to Chemistry Stack Exchange! (6) (c) Write the formula of Zeise's salt and draw its structure. The back donation is from filled metal d Is Mega.nz encryption vulnerable to brute force cracking by quantum computers? Cryptic Family Reunion: Watching Your Belt (Fan-Made), How to gzip 100 GB files faster with high compression. Explanation: Due to back bonding there is transfer of electrons from Pt to the ethylene pi orbitals, there is a decreased electron density around the Pt. His attempt to obtain such an explanation from Erich Hckel in 1939 failed, and it was Michael Dewar who in 1951 explained the nature of pcomplexes in molecular orbital terms. is it possible to read and play a piece that's written in Gflat (6 flats) by substituting those for one sharp, thus in key G? Both, the Cl- ion and ethylene are coordinated with Platinum ion, hence inside the coordination sphere. Polar covalent is the intermediate type of bonding between the two extremes. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Is this a possible explanation as to why sigma bonds are stronger than pi bonds? Ionic bonding models are generally presented as the complete loss or gain of one or more valence electrons from a metal to a nonmetal, resulting in cations and anions that If you look into the Molecular Orbital Diagram of Ethene, the picture will be more clear. The components: sodium and chlorine The process of [] "Salt dissolved in water" is a rough description of Earth's oceans. The bonds in salt compounds are called ionic because they both have an electrical chargethe chloride ion is negatively charged and the sodium ion is positively charged. Zeise thought of the structure of his salt as a product of the addition of PtCl2 to ethylene. The explanation of structure is given by Dewar-Chatt-Duncanson model In Zeise's anion, this rotational barrier has not been assessed. A compound with back bonding has pi-bonding character since it results after formation of sigma bond. H 2 O. His attempt to obtain such an explanation from Hckel failed, and it was Dewar who explained the nature of -complexes in molecular orbital terms in 1951. 3. It is especially common in the organometallic chemistry of transition metals with multi-atomic ligands such as carbon monoxide, ethylene or the nitrosonium cation. This air-stable, yellow, coordination complex contains an 2-ethylene ligand.The complex, which is primarily of historical interest, is commonly prepared from K 2 [PtCl 4] and ethylene in the presence of a catalytic amount of SnCl 2.The anion features square planar platinum(II). Zeise's salt Wikipedia , Zeises salt Wikipedia , Atoms In Motion Atoms In Motion Chapter 4 Salts , How doest the bonding takes place in zeises salt? Analysis of the barrier heights indicates that the -bonding between most metals and the alkene is But the answer given was 8 and the answer key didn't consider that bond as a sigma bond. Analysis of the barrier heights indicates that the -bonding between most metals and the alkene is weaker than the -bonding. Ionic and covalent bonds are the two extremes of bonding.
