Provide the structures of the fragments that result when the molecular ion of 2-heptanone undergoes fragmentation via McLafferty

stiks02 [169]

Answer:

See explanation

Explanation:

We have to start, remembering the mechanism behind the <u>McLafferty rearrangement</u>. The hydrogen in the g<u>amma carbon</u> (in this case, carbon 5) would be removed by a <u>heterolytic rupture</u> due to the <u>cation-radical</u> placed in the oxygen of the <u>carbonyl group</u>. Then we will have several heterolytic ruptures. Between <u>carbons alpha and beta</u> (in this case, 4 and 3) and a rupture in the <u>carbonyl group</u>. Due to these ruptures, <u>two double bonds would be formed</u>. One double bond in the alcohol cation-radical and the other one in the alkene.

See figure 1

I hope it helps!

A metal forms the fluoride MF3. Electrolysis of the molten fluoride by a current of 3.86 A for 16.2 minutes deposits 1.25 g of t

larisa86 [58]

<u>Answer: </u>The molar mass of the metal is 96.45 g/mol

<u>Explanation:</u>

The fluoride of the metal formed is $MF_3$

The oxidation half-reaction follows:

$M\rightarrow M^{3+}+3e^-$

Calculating the theoretical mass deposited by using Faraday's law, which is:

$m=\frac{M\times I\times t(s)}{n\times F}$ ......(1)

where,

m = actual mass deposited = 1.25 g

M = molar mass of metal = ?

I = average current = 3.86 A

t = time period in seconds = 16.2 min = 972 s (Conversion factor: 1 min = 60 sec)

n = number of electrons exchanged = $3mol^{-1}$

F = Faraday's constant = 96500 C

Putting values in equation 1, we get:

$1.25g=\frac{M\times 3.86A\times 972s}{3mol^{-1}\times 96500 C}\\\\M=\frac{1.25g\times 3mol^{-1}\times 96500 C}{3.86A\times 972s}\\\\M=96.45g/mol$

Hence, the molar mass of the metal is 96.45 g/mol

Suppose we have 100 g of each of the following substances. Which sample contain the greatest number of moles (F.W. = Formula Wei

Sindrei [870]

Answer:

100 g of water has the highest number of moles

Explanation:

Recall that the number of moles is obtained as given mass/formula weight

For HCl;

number of moles = 100g/36.5g/mol = 2.7 moles

For H2O;

number of moles = 100g/18g/mol = 5.5 moles

For MgCO3

number of moles = 100g/84.3 g/mol = 1.2 moles

For AlCl3

number of moles = 100g/133.3g/mol = 0.75 moles

For NaCl

number of moles = 100g/58.4 g/mol = 1.7 moles
