HArepresents the nucleus of hydrogen atom A and HB represents the nucleus of hydrogen atom B.When the two hydrogen atoms approach each other, the following two forces come into existence:(a) Attractive interactions in between:(i)  the nucleus HA an electron eB and(ii) the nucleus HB and electron eA(b) Repulsive interactions in between:(i) electron eA and electron eB and(ii) nucleus HA and nucleus HB.Since attractive forces overpower the repulsive forces, as a result, the enthalpy of the system decreases and a molecule of hydrogen is formed. For resonance, the double bond and lone pair must be present in conjugation with another double bond. Consider two hydrogen atoms A and B with electron eA and eB respectively. 2020 Zigya Technology Labs Pvt. © copyright 2003-2020 Study.com.

Answer to: Explain the resonance structures for the sulfite ion, SO3^{2-}. Hence shape is linear.BCl3:The central atom (B) has only three bond pairs and no lone pair. hybridisation. © Hence, the shape is Bent or V-shaped. Explain the resonance structures for the sulfite ion, SO3{eq}^{2-} The unhybridized p-orbitals of the two carbon atoms overlap sidewise with each other to form weak pi (. Earn Transferable Credit & Get your Degree, Get access to this video and our entire Q&A library. The central atom (B) has only three bond pairs and no lone pair. 74 pm) because the potential enthalpy of the system increases and curve shows an upward trend (dotted lines) and molecule becomes unstable. All rights reserved. Bent or V-shaped. The central atom (S) has two bond pairs and two lone pairs. Hence, the shape is Bent or V-shaped.PH3:The central atom (P) has three bond pairs and two lone pairs. Delhi - 110058. As the two atoms start coming closer to each other, the potential enthalpy continues to decrease (stage B). Write the resonance structures for SO3,   NO2 and. Hence, the shape is trigonal bipyramidal. Which hybrid orbitals are used by carbon atoms in the following molecules ? Three stable resonance structures can be drawn of SO 3 2-ion. Therefore, P = 6n + 2 – V = 6 * 4 + 2 – 26 = 0 There are no π electrons in SO 3-2 Therefore, the structure in Step 1 is a plausible Lewis structure of SO 3-2.. Hence the shape is tetrahedral. In the case of the hydrogen molecule, the bond length is 74 pm. BeCl2:Lewis dot structure Cl: Be : Cl. The resonance is the description of the electronic structures or an ion by means of several schemes of the pairing of electrons, with the features of each scheme contributing to the description. https://www.zigya.com/share/Q0hFTjExMDg2NjU0. Resonance and resonance hybrid structures of O3, SO3, SO2, CO3-2, SO4-2, PO4-2,NO3- he phenomenon of resonance was put forward by Heisenberg to explain the properties of certain covalent molecules. 74 pm) because the potential enthalpy of the system increases and curve shows an upward trend (dotted lines) and molecule becomes unstable. Most covalent molecules have a unique Lewis formula (dot structure), which explains the bonding in … between two hydrogen atoms at this stage is referred to as bond length. The central atom (Si) has four bond pairs and no lone pair. Hence, the shape is trigonal bipyramidal.H2S: The central atom (S) has two bond pairs and two lone pairs. The molecular orbital structure of ethylene: In ethene molecule, each carbon atom undergoes sp, hybrid orbital of one carbon atom overlaps axially with one sp, hybrid orbital of the other carbon atom to form sigma (σ) C - C bond. Enthalpy diagram: When two hydrogen atoms are at an infinite distance from each other, there is no interaction between them and therefore, the enthalpy of the system is assumed to be zero in this state (stage-A).
