Sir cn you tell me that can we use this formula
First, let's determine the number of moles of carbon atoms by using molar mass. Then, using Avogadro's number, we can find the number of C atoms:
*1 mole of C3H8O= (12.0x3)+(1.0x8)+(16.0x1) = 60.0g/mol
25.0 grams C3H8O x (1 mole C3H8O/60.0 grams) = 0.417 mol
0.417mol C3H8O has (3 x 0.417 moles) C atoms = 1.251 moles C atoms
1.251 moles C atoms x(6.022x10^23 atoms/mol) = 9.42x10^23 C atoms.
The answer is in 3 significant figures, as that's what we have in the given, and we matched it with our rounding of the atomic masses from the periodic table.
You can do this all in one equation written left to right, just exclude the intermediate answers. Just easier to show it this way on the computer screen.
Answer:
See explanation below
Explanation:
When the bromine (Br₂) reacts in presence of FeBr₃ with the isopropylbenzene, the isopropylbenzene is a ring activator, therefore, it will promote the substitution in the ortho and para positions. However, as the Isopropyl is voluminic, the ortho position would have steric hindrance and hence, this product is not formed in greater proportions. Instead, the para position becomes more available to reaction, and this product is formed in majority.
The mechanism of reaction can be seen in the following picture, along with the products of the reaction
Hope this helps
Oxygen is needed for Cellular Respiration. Just as Carbon Dioxide is needed for Photosynthesis. Oxygen is required to create ATP in the process.
