The structure of 1-methoxypropane is CH₃-CH₂-CH₂-OCH₃
I will label the carbons A-D from left to right.
A B C D
CH₃-CH₂-CH₂-OCH₃
In a proton NMR spectrum, we are looking at the chemical shifts of each unique hydrogen atom, and the splitting patterns tell us how many hydrogens are attached to the adjacent carbon. Therefore, the signal from the protons on carbon A will be split by the protons on carbon B, and the signal for protons on carbon A will have a splitting pattern equal to n+1, where n = number of hydrogens on the adjacent carbon.
Therefore, for the protons on carbon A, there are two neighbouring protons and these will give a splitting patter of 3 peaks, also known as a triplet.
Protons on carbon A: 2 adjacent protons result in a triplet signal.
Protons on carbon B: 5 adjacent protons result in a sextet signal.
Protons on carbon C: 2 adjacent protons result in a triplet signal.
Protons on carbon D: 0 adjacent protons result in a singlet signal.
Answer:
THE answer is all of above
Explanation:
Answer:
ICE Table Figure
a. 67.37 g 
b. 35.62 g 
c. 58.61 g
Explanation:
For the <u>ICE table </u>we have to keep in mind that we have 4 moles of
and 1 mol of
and the reactives are consumed, so for
we will have -4X and for
we will have -X. Follow the same logic we will have -4X for
.
a. <u>Mass of the product</u>
Molar mass of
= 256.52 g/mol
Molar mass of
=70.9 g/mol
Molar mass of
=135.03 g/mol
We have to find the limiting reagent in the reaction:



Divide by the coefficients in the balanced reaction:


The limiting reagent would be 
Now is posible to calculate the amount of
produced:

b. <u>Mass in excess</u>


C. <u>87%Yield</u>

Answer: the certain of a 10ml pipet is listed as, 10.00 0.02,
Explanation: those numbers are close to 4 significant figures as in (10ml) around the amount you're looking for. , hope that makes sense!
