The aqueous hydroxide-promoted reaction of the compound with 2,2-dimethylpropanal (pivalaldehyde) at elevated temperature gives

ivolga24 [154]

Answer:

The mechanism of this reaction i shown on the second uploaded image

The final product of the reaction is shown on the third uploaded image

The hydroxide would be first mixed with the ketone group before the aldehyde is added

Explanation:

The compound given in the question is 2,2-dimethylpropanal (pivalaldehyde) the structural formula is shown on the first uploaded image

looking at the structurally formula we can see that the hydroxide promoted reaction of this compound would be between the ketone and aldehyde functional group present in this compound in the presence of a hydroxide

Now this process of the reaction is this

The $OH^-$ is first made to react with the ketone group

Then the aldehyde is added

What happens is that that the $OH^-$ would search for an acidic proton because it is a base and this acidic proton is present in ketone and absent in aldehyde group hence the reason for the first reaction with the ketone group before the aldehyde is added

Merits of modern periodic table?

ANEK [815]

Answer:

<h3>Merits of modern periodic table:</h3>

The wrong position of some elements like argon, potassium, cobalt and nickel due to atomic weights have been solved by arranging the elements in the order of increasing atomic number without changing their own places.
The isotopes of some element have the same atomic numbers. Therefore, they find the same position in periodic table.
It separates metals from non-metals.
The groups of the table are divided into sub groups A and B due to their dissimilar properties which make the study of elements specific and easier.
The representative and transition elements have been separated.

Hope this helps...

Good luck on your assignment...

For the reaction represented by the equation Fe + H2O ® Fe2O3 + H2, how many moles of iron(III) oxide are produced from 285 g of

schepotkina [342]

Balanced equation: 2Fe + 3H2O → Fe2O3 +3H2

Convert g to mols:

285/55.845 = 5.1034 mols

Mole ratio of Iron and Iron (III) Oxide: 2:1

5.1034/2 = 2.5517 mols
