Answer:
dimethoxy(phenyl)methanol
Explanation:
For this question, we have to remember the <u>mechanism of the Grignard reaction</u>. In this case, <u>phenylmagnesium bromide</u> is our <u>nucleophile</u>, a carbo-anion is produced (step 1). Then this <u>carbo-anion</u> can <u>attack</u> the <u>carbonyl group</u> in the <u>dimethyl carbonate</u>, the double bond is delocalized into the oxygen producing a <u>negative charge</u> (step 2). Finally, with the addition of the h<u>ydronium ion</u> (), the anion can be protonated to produce the <u>alcohol</u> (dimethoxy(phenyl)methanol) (step 3).
See figure 1

The main job of these systems is to break down food and for it to exit the body after taking out of it what is necessary such as nutrients
Answer:
The polar covalent bond is much stronger in strength than the dipole-dipole interaction. The former is termed an intramolecular attraction while the latter is termed an intermolecular attraction. So now we can define the two forces: Intramolecular forces are the forces that hold atoms together within a molecule.
The equation for molarity is molarity equals moles divided by liters of solution. Knowing this, it's just simple algebra of 2 moles divided by .5 liters, equaling 4M (M standing for molarity).
384.72 J is the heat of fusion of the substance.
<h3>What is the heat of fusion? </h3>
It is the change in the value of the enthalpy by providing energy i.e. heat, for a specific quantity of the substance.
Given data:
Heat of fusion =?
Mass of substance = 8.4 g
Unknown:
Amount of energy required to melt the given mass = 45.8 cal
Solution:
To solve this problem, the amount of energy required to melt the substance is given as;
H = m L
m is the mass
L is the heat of fusion
Insert the given parameters and solve;
H = 8.4 g x 45.8 cal = 384.72 J
Hence, 384.72 J is the heat of fusion of the substance.
