Vanillin, C8H8O3, is the active ingredient in vanilla flavoring. It contains a six-membered aromatic ring with an aldehyde group
on carbon 1, an alkoxy group (ether) on carbon 3, and a hydroxyl group (alcohol) on carbon 4. Draw the structure of vanillin.
1 answer:
Answer:
The answer is in the picture attached
Explanation:
A six-membered aromatic ring is one of the most common structures in natural compounds.
The aldehyde group in position one consist in one carbon double-bonded to oxygen and bonded to hydrogen.
The alkoxy group in position three consist in a oxygen bonded to an alkyl group (The simplest alkyl group is methyl -CH₃-).
There is, in position four, an hydroxyl group -OH. bonded to this six-membered aromatic ring.

<u>Answer:</u> The concentration of in the cell is
<u>Explanation:</u>
We are given:
<u>Oxidation half reaction:</u>
<u>Reduction half reaction:</u>
The substance having highest positive potential will always get reduced and will undergo reduction reaction. Here, fluorine will undergo reduction reaction will get reduced.
Here, tin will undergo reduction reaction and will get reduced.
Oxidation reaction occurs at anode and reduction reaction occurs at cathode.
To calculate the of the reaction, we use the equation:
Putting values in above equation, we get:
To calculate the EMF of the cell, we use the Nernst equation, which is:
where,
= electrode potential of the cell = 0.660 V
= standard electrode potential of the cell = +0.624 V
n = number of electrons exchanged = 2
= ?
Putting values in above equation, we get:
Hence, the concentration of ions is
