Reactions of Aldehydes
and Ketones Compounds
Using the drawing pallet on the right, draw the structure
of the major organic product for the reaction shown below:
A Wittig reagent adds to the carbonyl carbon through the
anionic carbon. The intermediate betaine decomposes to give
the phosphine oxide and the alkene.
Using the drawing pallet on the right, draw the structure
of the major organic product for the reaction shown below (show stereochemistry):
A Grignard reagent will add to a ketone to form a
tertiary alcohol. The most likely product will have the two methyl groups trans- due to steric effects on the attack of the Grignard reagent.
Using the drawing pallet on the right, draw the structure
of the major organic product for the reaction shown below:
Diethylaluminum nitrile is a convenient reagent for the
conjugate addition of a nitrile group.
Using the drawing pallet on the right, draw the
structure of the major organic product for the reaction
shown below:
Hydroxylamine adds to ketones & aldehydes to form
simple oximes (a carbon-nitrogen double bond and the
nitrogen is bonded to a hydroxyl group).
Using the drawing pallet on the right, draw the structure
of the major organic product for the reaction shown below:
BH4- is a mild reducing agent and
will convert a ketone into the corresponding secondary
alcohol.
Using the drawing pallet on the right, draw the structure
of the major organic product for the reaction shown below:
Ketones react with acidic alcohols to form ketals
(1,1-diethers).
Using the drawing pallet on the right, draw the structure
of the major organic product for the reaction shown below:
CrO3 in H2SO4 is a
powerful oxidizing agent and will oxidize an aldehyde to
the corresponding carboxylic acid.
Using the drawing pallet on the right, draw the structure
of the major organic product for the reaction shown below:
Amines react with aldehydes and ketones to form
imines (a carbon-nitrogen double bond).
Using the drawing pallet on the right, draw the structure
of the major organic product for the reaction shown below:
In the presence of an acid catalyst, alcohols react with
ketones & aldehydes to form ketals and acetals. In this
case, a cyclic ketal is formed (a cyclic,
1,1-diether).
Using the drawing pallet on the right, draw the structure
of the major organic product for the reaction shown below.
Dialkylcopper lithium reagent reacts with a-b unsaturated ketones and aldehydes to
add the alkyl group to the b-carbon of the conjugated system.
That is correct!
Sorry, that is not correct. You should modify your
structures and try again.
