The multiplicity that would be in a 1H NMR spectrum for the indicated proton(s) is triplet.
The correct answer is an option (b)
NMR spectroscopy is used to examine the structure of molecules.
Another type of additional data available from 1H NMR spectroscopy is called multiplicity.
It is useful because it reveals how many hydrogens are on the next carbon in the structure.
1H NMR is a technique to confirm the structure of organic compounds or those that contain protons.
In 1H NMR technique, multiplicity provides information about the number of proton neighbors for a particular proton atom or group of atoms (neighboring typically refers to atoms within 3 bonds).
A solution-state proton spectrum is relatively fast to acquire, compared with other nuclei, and a lot of information about the structure of a compound can be deduced from it.
Therefore, the multiplicity that would be in a 1H NMR spectrum for the indicated proton(s) is triplet.
The correct answer is an option (b)
Answer:
The pattern is + 10.
Step-by-step explanation:
13 + 10 = 23
23 + 10 = 33
33 + 10 = 43
...and so on.
I hope this helped! :-)
Step-by-step explanation:
2 (yellow) / 3.5 (blue)
that means, out of 2+3.5 = 5.5 units 2 are yellow, and 3.5 units are blue.
now in a 3 / 4.5 ratio we have 3+4.5 = 7.5 units, where 3 units are yellow and 4.5 units are blue.
let's bring both ratios to the same denominator (bottom part of the fraction).
if we multiply 3.5 by 2 we get 7. and multiplying 4.5 by 2 gives us 9.
and the smallest common multiple of 7 and 9 is 63.
so, let's bring both fraction to .../63.
3.5 × 2 × 9 = 63
so, the ratio is
2×2×9/63 = 36/63
and
4.5 × 2 × 7 = 63
so, that ratio is then
3 × 2 × 7 / 63 = 42/63
now we can see clearly that the first ratio
2/3.5 = 36/63 has fewer units of yellow in the mix than the second ratio
3/4.5 = 42/63.
so, the second mixture is more yellow.
Answer:
p = kh.
Step-by-step explanation:
The amount of pay p = k times the number of hours worked.
The equation is p = kh.
