Answer:
The answer is neopentyl alcohol. (CH₃)₃C-CH₂-OH
Explanation:
This alcohol cannot be synthesized by the hydroboration–oxidation of an alkene since the reaction of hydroboration–oxidation go through steps that involved the addition of BH₃ into the original structure. In the case of neopentyl alcohol, if we carry out retro synthetic by the hydroboration–oxidation, we will find the original alkene is (CH₃)₃C=CH₂ which is impossible since the center carbon atom has 5 bonds.
The condition for hydroboration–oxidation reaction is that the alkene must have the structure of R-CH=CH₂
Answer: 121.95587 g/mol
Explanation:
- The atomic mass of aluminum is 26.98154 g/mol.
- The atomic mass of phosphorous is 30.97673 g/mol.
- The atomic mass of oxygen is 15.9994 g/mol.
Therefore, the molecular mass is:
![26.98154 +30.97673 +4(15.9994)=\boxed{121.95587 \text{ g/mol}}](https://tex.z-dn.net/?f=26.98154%20%2B30.97673%20%2B4%2815.9994%29%3D%5Cboxed%7B121.95587%20%5Ctext%7B%20g%2Fmol%7D%7D)
The answer is sodium chloride.
Explanation:
Sodium chloride refers to table salt, and is the most abundant of salts found in seawater.
In 1803AD, Osmium was discovered by Smithson Tennant when dissolving an impure sample of platinum in aqua regia, a mixture of hydrochloric and nitric acids. He was able to determine that the black powder left behind after dissolving the platinum was actually a mixture of two new elements, indium and osmium.
•Osmium is a bluish-white and shiny metal.
•Osmium is very hard and is brittle even at very high temperatures.
•Osmium has the lowast vapor pressure and the highest melting point among the platinum group of metals.
•Osmium's density is slightly more than iridium hence is credited as the heaviest element.
