Which compound matches the ir spectrum best?

Chemistry
1 answer:
Maurinko [17]3 years ago
4 0
Small peak at 3000large peak at 1685F: it contains two benzene rings that is connected by a bunch of carbons and ketone-Explanation: The spectrum shows a stretching absorption consistent with a ketone functional group: carbonyl C=O stretching at ~1685 cm-1. (An aldehyde, by contrast, would also show a ~2700 cm-1 absorption for the carbonyl C-H stretch.) The C=O stretching frequency is consistent with an aromatic ketone, such as in compound F (1,4-diphenyl-1,4-butanedione). In contrast, an aliphatic ketone absorbs at higher energy (~1710 cm-1). The spectrum also shows the typical ~1600 & ~1500 cm-1 absorptions of a phenyl group.

synthetic Plastics are made by linking many simple carbon molecules together to form much larger molecules. the process is calle
Nutka1998 [239]

Answer:

Polymerization

Explanation:

Several natural and man-made organic compounds are enormous molecules which contains hundreds of thousands of atoms per molecule.

The giant molecules formed are produced through the process of polymerization.

Polymerization is the linking of monomers through chemical reactions to form long chain polymer molecules.

Monomers are small molecules that are joined to form polymers.

Synthetic plastics are derieved from synthetic polymers. These synthetic materials are very useful and vital due to their great size. Their size premits a certain complexity of structure which makes the molecules disposed in a regular pattern with respect to one another. They stretch out nearly to alongside of one another or coil up independently. The polymerization of monomers to form plastics fosters the various uses these giant molecules are put to.

How do you measure moles
wlad13 [49]

Answer:

Answers may vary

Explanation:

Mol is the amount of molecules in something. Mol are similar to donuts, if you have a dozen of something you have 12 of them. If you have a mol of Hydrogen gas you 6.02•10^23 molecules of Hydrogen gas. If you are taking a chemistry class you will probably receive questions involving converting grams to mol and vice versa.

Converting Grams to Mol:

grams of x•(1/molecular mass of x)

note: you can find molecular mass of x by looking at the masses of the elements you need to add up in the periodic table

Converting Mol to Grams:

mol of x•(molecular mass of x)

When is an electric charges neutral ??
dangina [55]

Answer:

Atoms of matter are electrically neutral because their nuclei contain the same number of protons as there are electrons surrounding the nuclei. Electric current and charged objects involve the separation of some of the negative charge of neutral atoms.
