Please answer them. Thanks!

Please answer all multiple choice don't justify just give me the answer

Answer question one please.

I'm confused on part 2-3 of the questions on the difference between infrared hymns and viable and how those photons are absorbed

Answer correctly please

SOLVE STEP BY STEP IN DIGITAL FORMAT Explain the underlined paragraph, make it extensive and unambiguous, support its foundations in biochemistry and quantum mechanics. The sample substance used is 1,1-diphenyl-2-picryl-hydrazyl (DPPH). This organic compound is a relatively stable free radical which has an unpaired valence electron at one atom of the nitrogen bridge. The orbital motion of the electron is almost cancelled by the molecular structure. Therefore the g-factor of the electron is almost equal to that of a free electron. In its polycrystalline form the substance is very well suited for demonstrating electron spin resonance because it has an intense ESR line, which, due to exchange narrowing, has a small width.

What is wrong with the Lewis structure depicted below? [Image description: A Lewis structure with a C atom singly bound to three H atoms and a N atom. The N atom also singly bound to two O atoms.

Research ( 4 ) Question is in the photo below

Why pi(π) bond needed a longer wavelength than the sigma bond? Please shortly answer at your own words. Answer should be to the point(specific 4-5 lines).

How do I count the valence electrons on a carbon radical?

Finding the structures of new molecules and/or confirming the structures of synthesized molecules is central to organic chemistry. Mass spectrometry and infrared spectrometry are two important techniques to help with characterizing a molecule. Talk about these two techniques and the specific chemical information they provide.

Infrared spectroscopy is most useful for Please choose the correct answer from the following choices, and then select the submit answer button. Answer choices determining the molecular structure of an unknown compound. differentiating between functional groups. determining the exact chemical formula of an unknown compound. determining the molecular mass.

Examine the geometry of the molecule in the 3D window. Use the geometry to determine the bond types. carbon-carbon approximate bond type length single - 0.15 nm double - 0.13 nm aromatic - 0.14 nm • Double-click on an atom, and then move cursor over another one to get a distance (click off of the molecule to end) • Double-click on an atom, click on a second and move cursor over a third to get the angle about the second atom (click off of the molecule to end) JSmol Are there one or more rings in the molecule that are completely planar? Do the C-C distances in all of the rings fall between 0.135 and 0.145 nm? Are the rings in the compound aromatic, non-aromatic or mixed?

Riboflavin absorbs UV-visible light making the electrons in the molecule more energetic. As a result, the more energetic electrons move from the 'ground state' electronic energy level to higher electronic energy levels known as 'excited states’. Which of the following statements is NOT true regarding how the ‘excited state’ molecule loses energy and returns to the 'ground state'? a) non-radiative losses via bond vibration and rotation within the molecule b) non-radiative losses via phosphorescence c) non-radiative losses via collisions with other molecules d) radiative losses via fluorescence emission of light

Chemistry This is a molecule of aspirin, a very commonly used painkiller.       Draw up a table to show the KEY peaks that you would expect to see in the infrared spectrum of aspirin, identifying which bond has given rise to which peak.

Please answer this question shortly at your own words. Answer should be to the point.

answer EACH PART very clearly please dont make it confusing, this is chem 2600, physical chemistry course!!!! please draw it seperately clearly!! fast answer .
