For both PSCl 3 and POCl 3, the calculations show that the dissociative electron attachment process is close to thermoneutral. In contrast to PSCl 2, the calculations imply that EA ( POCl 2 ) is slightly greater than EA(Cl). Comparison is made between the present study of electron attachment to PSCl 3 and our earlier work on attachment to POCl 3, and G3 calculations are reported here for neutral and anionic POCl 2 and POCl 3. A natural population analysis was performed to obtain the charges associated with each atom in the molecules in order to estimate how the attached electron is distributed. BCIH, BCIH2 Question Rank the following molecules in order of increasing dipole moments: BCl3.BCL,H.BCIH See Hint See Periodic Table 1st attempt Molecule (3 items) (Drag and drop into the appropriate areal This question hasn't been solved yet Ask an expert Question: BCls. The calculations indicate that the electron affinity EA ( PSCl 2 ) is slightly smaller than EA(Cl), which may account for the observed branching fractions for PSCl 2 − and Cl − in the low-pressure experiments. Gaussian-3 (G3) calculations were carried out for PSCl 3 and PSCl 2 neutrals and anions to aid in interpretation of the experimental results. In contrast to the low-pressure data, the parent anion product channel ( PSCl 3 − ) was observed (along with the dissociative channels), and increased in importance with N 2 pressure. Attachment to PSCl 3 was also studied at high pressure (9–93 kPa) of N 2 in an ion mobility mass spectrometer, at 298 K. The polarization of the 3 B-Cl bonds exactly cancels out, so BCl3 has no dipole moment. The FALP data suggest that there is an activation energy of about 17 meV for production of PSCl 2 −. For BCl3, the geometry is an equilateral triangle of Cl atoms, with the boron atom in the center of the triangle. Attachment in 133 Pa of He gas yielded only the dissociative ion products PSCl 2 − and Cl −. ![]() This rate constant represents an attachment efficiency of about 14%. These experiments yielded an electron attachment rate constant of 5.1×10 −8 cm 3 s −1 that was found not to change significantly in the 298–550 K temperature range. Measurements of rate constants and branching fractions were made in a flowing-afterglow Langmuir-probe (FALP) apparatus. Question: If you react BCl3 to make the ion BCl32, is this ion planar Does the molecule BCl2Br have a dipole moment If you react BCl3 to make the ion BCl32, is this ion planar Does the molecule. Electron attachment to PSCl 3 was studied in 133-Pa pressure of helium gas at temperatures from 298–550 K.
