Determine whether the number of IR and Raman active stretching
modes could be used to determine uniquely whether a sample of gas is
BF3, NF3, or ClF3.

Homework Answers

Answer #1

For the molecules,

BF3 without any lone par on boron would have a different set of symmetry operation and active modes for Ir and Raman when compared to NF3 with a lone pair of electron on Nitrogen. Similarly ClF3 with 3 lone pair of electrons on Cl would have a completely different symmetry operation and valid Ir and raman modes.

These features thus determine the differences between the given three gases and thus a sample of gas can easily be identified knowing the symmetry operation and Ir and Raman active modes data experimentally.

The following four problems are used by a physicist to determine whether (LiH)2+ could be a stable species in an ionized gas. Now, let rLiH vary continuously from infinity to zero. i) Make a sketch of the potential energy of the (LiH)2+ molecular ion as a function of rLiH. Let the energy of isolated atoms/ions be defined as zero. ii) Identify the region of this potential energy curve that is dominated by the attraction of the electrons to the nuclei....

Before the advent of modern spectroscopic techniques, such as NMR and IR spectroscopy, chemists typically determined whether a functional group was transformed into another during a reaction by performing chemical tests, where the reagents would react with the new functional group but not the old one (or vice versa) causing an observable reaction to occur, such as gas bubbles or a solid precipitate. Find a chemical test that you could have used to determine whether or not the nitro group...

Gender and number words: Chang, Sandhofer, and Brown (2011) wondered whether mothers used number words more, on average, with their preschool sons than with their preschool daughters. Each participating family included one mother and one child—either female or male. They speculated that early exposure to more number words might predispose children to like mathematics. They reported the following: “An independent-samples t test revealed statistically significant differences in the percentages of overall numeric speech used when interacting with boys compared with...
