The Quora Platform does not have a direct text formatting features. F 2 has a bond order of 1. A material aligning itself with the applied field is called paramagnetic material. I'll tell you the Paramagnetic or Diamagnetic list below. By constructing a molecular orbital picture for each of the following molecules determine whether it is paramagnetic or diamagnetic.

Which of the following molecule does not exist due to its zero bond order? I) H2+ II) He2 III) B2 IV) Be2 2- V)O2. paramagnetic: contains one or more unpaired electrons. ? Di helium cation (He2+) possess three electron over all two are present in bonding sigma molecular orbital and are paired and one electron in antibonding sigma orbital which is unpaired. Indicate whether F-ions are paramagnetic or diamagnetic. The Question containing Inaapropriate or Abusive Words, Question lacks the basic details making it difficult to answer, Topic Tagged to the Question are not relevant to Question, Question drives traffic to external sites for promotional or commercial purposes, The Answer containing Inaapropriate or Abusive Words, Answer drives traffic to external sites for promotional or commercial purposes. Bond Order = 1/2(10 - 8) = 1. 1. The electron would be removed from the pi orbital, as this is the highest in energy. C. Predict Which Is Paramagnetic Diamagnetic. 3. In contrast with this behavior, diamagnetic materials are repelled by magnetic fields and form induced magnetic fields in the direction opposite to that of the applied magnetic field. Paramagnetic elements are strongly affected by magnetic fields because their subshells are not completely filled with electrons. This problem has been solved! Draw The Molecular Orbital Diagram For Each And Explain Your Answer. Answer posted is not solving the query properly. Calculate the bond order for this ion. When we draw MO diagram for dihydrogen anion ( H2-) we find one unpaired electron in antibonding sigma orbital. All three of the species you wrote here are paramagnetic, assuming the "2" is a subscript in each of the structures. 2) H2+ A compound will be paramagnetic if it has an unpaired electron (unp e-). Lindau 3 years ago 0. Otherwise it is 3. 1 decade ago. 4) CO2. This case is said to be diamagnetic. Which of the following is diamagnetic:- They are, as you wrote here, [math]O_2, O_2^+, O_2^-[/math]. among the following reactions find those that are redox reactions? Diamagnetic substances are those which have a tendency to move from stronger part to the weaker part of the external magnetic field. Your one-stop Counselling package for JEE Main, JEE Advanced and BITSAT, Your one-stop Counselling package for NEET, AIIMS and JIPMER. Be: 1s 2 2s 2 subshell is filled. For For He2+: a. Construct mo diagram (assign electrons to MO delivered in online submission). NO + 5+6-1 = 10 valence electrons (σ2s) 2 (σ * 2s) 2 (π2p x) 2 (π2p y) 2 (σ2p z) 2 Here all of the electrons are paired so NO + is diamagnetic and the answer is B. Ne22 o22 f22 o22 none of the above are paramagnetic. It is an exceptional case. Lv 7. Which is the light metal available with better Hardness ? Question: Use Molecular Orbital Theory To Determine Whether He2 Or He2+ Is More Stable. Is Be2+ diamagnetic or paramagnetic? 4) He2+. Let it be H2- ,H2+ or He2+ ; there's an unpaired electron i.e, they are paramagnetic. Let it be H2- ,H2+ or He2+ ; there's an unpaired electron i.e, they are paramagnetic. 1) N3 Ne22 o22 f22 o22 none of the above are paramagnetic. To know the magnetic character of molecules we can use MO diagram. For diamagnetic character, there should not be any unpaired electron in the molecules formation. 3) NO2- Recall that paramagnetic means it contains at least one unpaired electron and diamagnetic is the lack thereof. Is He_2+ Paramagnetic Of Diamagnetic?
