Sep 01, 2019 · Sol. 5or6. If existence of $\mathrm{Be}_{2}$ is considered in atomic form or very weak bonded higher energetic species having zero bond order then it is diamagnetic , then answer will be 6. But if existence of molecular form of $\mathrm{Be}_{2}$ is not considered then magnetic property can’t be predicted then answer will be 5. Critical thinking questions 1. Using the Lewis structure of CO 2 from Model 2, work out the arrangement of the electron pairs and hence the shape of the molecule. 2. Using the Lewis structures of NH 4 + and PCl 3 from Model 2, work out the arrangement of the electron pairs and draw the shapes of these molecules. Apr 26, 2015 · A) square planar. The answer is A) square planar. Start from the Lewis structure of the tetrafluoroborate ion, BrF_4^(-). The molecule will have a total of 36 valence electrons - 7 from bromine, 7 from each of the four fluorine atoms, and one extra electron to give the ion the -1 charge. The bromine atom will be bonded to each of the four fluorine atoms via single bonds for a total of 8 of the ... As discussed before the frequencies below 150 cm −1 can be assigned to the stretching modes + C–H⋯A − describing the anion–cation interaction. 49 In Fig. 4 it is shown that the FIR spectra of ILs I–III are similar in the anion–cation stretching region between 100 and 150 cm −1. But one IL is different.
