Question: A optically active compound, C5H10O, exhibits IR absorption at 1730 cm-1.
Its carbon NMR shifts are given below. The number of hydrogen's at each carbon, determined by DEPT, is given in parentheses after the chemical shift.
13C NMR: δ 22.6 (3), 23.6 (1), 52.8 (2), 202.4 (1)
Draw the structure of this compound in the window below
Explanation:
3-methylbutanal is a butanal substituted by the methyl group at the 3rd position. It is a volatile constituent in the olive. Also, it is used as a flavoring agent and a plant metabolite, it is also a Saccharomyces cerevisiae metabolite. It is also called as the Isovaleraldehyde organic compound. The liquid is colorless at STP, and also found in very low concentrations. It is also seen to be produced commercially for different use. Mostly used compound reagent in the preparation of pharmaceuticals and pesticides.
Answer:
i would say 10, so the anser is A.
Explanation:
because there are the same number of protons and electrons, therefore for a regular O, you are supposed to have only 8 protons, but it is charged, thus, whatever the charge is will be taken into consideration into how much the proton and electron doe it have. Thus, for this case, it has 10, because the charge is negative and you have 8 electron plus 2 = 10.
B) gets smaller
The concentration of hydrogen atoms is inversley related to its pH.
In an aqueous solution, the hydronium ion concentration is equivalent to the hydrogen ion concentration because the hydrogen ion exists as the hydronium ion. The pH of pure water is 7, and:
pH = -log[H+]
7 = -log[H+]
[H+] = 1 x 10⁻⁷
Therefore, the hydronium ion concentration in pure water is also 1 x 10⁻⁷.
Answer:
The electron moves by charge attraction
Explanation:
The electrons move by static attraction. Electrons are negatively charged particles that are closely connected with the atoms. The electrons are always delocalized. This means that they belong to no particular atom, but instead, are freely moving around. It is the electrons that help with the transfer of charge in the molecule. In addition, it is the delocalized electrons that carry the charge in the solution. Finally, it is the electrons that make the solution to conduct current.
