Answer:
Both reactions proceeds through nucleophilic acyl substitution reaction
Explanation:
- Both these two reactions proceeds through nucleophilic acyl substitution reaction where phenyl magnesium bromide replaces one ethoxide ion.
- Then another another equivalent of phenyl magnesium bromide give nucleophilic addition reaction with resulting keto group to produce triphenylmethanol
- Full reaction mechanism has been shown below
Answer:
1) 100
2) 22
3) 39
4) 6
5) 2b + 6
6) 8
7) 4n + 20
Explanation:
If B is the midpoint of AC and C is the midpoint of BD, means that all 3 parts are equal. AB = BC = CD
1) If AB = 50 then AC = AB + BC = 50 +50 = 100
2)if BD = 44 then is CD = 44 - BC ⇔ CD = 44 - 22 = 22
3) if AC = 26 and AC = AB + BC then each part is 13
AD = AC + CD = 26 +13 = 39
4)if CD = 6 then AB = 6 Because all single parts are equal
5) if AC = 4b + 12 then is AB the half of it = 2b +6
6) if AD = 24 then AB = 1/3 of it = 8
7)if BC is 2n + 10 then is AC = 2x BC = 4n + 20
Answer:
Explanation:
The concept of Lewis Acid and base was applied in determining the product formed from the reaction of the lewis acid and the lewis base.
According to G.N Lewis - an american who worked and elaborated more on the definition of acids and bases. He defined an acid as an electron pair acceptor and a base as an electron pair donors.
One of the application of lewis theory is in the reaction to test for the presence of copper(ii) ions by the addition of ammonia to form a clear blue solution of tetraammine.
The reactions of the lewis acid to each of the base is as shown in the attached file.
Answer:
14 is this value for a molecule of 
.
Explanation:
Lewis-dot structure : It shows the bonding between the atoms of a molecule and it also shows the unpaired electrons present in the molecule.
In the Lewis-dot structure the valance electrons are shown by 'dot'.
Number of total outer valence electrons is carbon = 4
Number of total outer valence electrons is hydrogen = 1
Number of total outer valence electrons is chlorine = 7
For total number of outer electrons is
14 is this value for a molecule of .
<h3>
Answer:</h3>
5.6 L
<h3>
Explanation:</h3>
We are given;
- Initial volume, V1 = 3.5 L
- Initial pressure, P1 = 0.8 atm
- Final pressure, P2 = 0.5 atm
We are required to calculate the final volume;
- According to Boyle's law, the volume of a fixed mass of a gas and the pressure are inversely proportional at a constant temperature.
- That is; P α 1/V
- Mathematically, P=k/V
- At two different pressure and volume;
P1V1 = P2V2
In this case;
Rearranging the formula;
V2 = P1V1 ÷ P2
= (0.8 atm × 3.5 L) ÷ 0.5 atm
= 5.6 L
Therefore, the resulting volume is 5.6 L
