Answer:
The stereochemistry of the dienophile is retained in the product.
Explanation:
The main properties of the<em> Diels-Alder reaction</em> are:
- The diene can react only when it adopts the s-cis conformation.
- Electron-donating substituents in the diene increase reaction rate.
- Electron-withdrawing substituents in the dienophile increase reaction rate.
- The stereochemistry of the dienophile and of the diene is retained in the product.
Answer:
B
Explanation:
by using formula
pH = –log(0.0025) = –log(25/10⁴)
= 4 – log(25) = 2.60
Notice that in the equation given, there is 1 mol of Mg3N2
and 6 mol of H2O. Consequently, the question is requesting, if we took 2.5 mol
of Mg3N2, how many mol of H2O would be essential to complete a similar reaction
-- in quintessence, multiplying everything by 2.5:
the solution would be: 6 * 2.5 = 15 mol
This equation represents a single replacement reaction. Single replacement reactions consist of one element reacting with one compound on the reactant side (left side of the equation) and they form one new element and one new compound on the product side of the equation (right side).
