AAMI CHEM FOR EMBALMERS WEEK#3 EXAM REVIEW QUESTIONS WITH
CORRECT ANSWERS
Aldehydes - Answer-Defined as an organic compound containing one or more (-CHO)
groups
Aldehydes functional group - Answer-CHO
Aldehydes general formula - Answer-R-CHO
Aldehydes name comes from - Answer-Alcohol deprived of HYDrogen
•It's one of the many ways it gets its name
You can partially oxidize a primary Alcohol to get an aldehyde, true or false? - Answer-
True
•Partial Oxidation
You can create an aldehyde from a hydrocarbon by replacing 2 hydrogen atoms on the
same carbon with an atom of an oxygen, true or false? - Answer-True
•Full oxidation
Another way to form and aldehyde is to reduce in organic acid. Just by using the line
formulas and - Answer-Counting the number of hydrogen and oxygen, you can see how
this is done
As a group Aldehydes compromise the largest percentage of - Answer-Disinfectants
and preservative chemical agents that are Routinely incorporated into Embalming fluids
naming aldehydes - Answer-1.Replace the (E)ending of the saturated Hydrocarbon with
(AL) Just as you would (OL)for alcohol
2.And aldehydes other name is derived from the prefix of its corresponding organic
acid's source.
Some organic compounds that contain a carbon in their function need only hydrogen
atom in the alkyl (Radical) position; H-CHO, therefore you must - Answer-Count the
carbon with in the functional group when you are naming an aldehyde
When you are drawing a structural formula for an aldehyde from its name you must -
Answer-Draw the functional group 1st;
•count the carbon in the functional group,
•then place the correct number of Carbons in the formula
, Aldehydes groups - Answer-•Monoaldehydes
•Dialdehydes
•Cyclic or Aromatic Aldehydes
Monoaldehydes - Answer-Contain 1 CHO group
Dialdehyde - Answer-an organic compound containing two aldehyde
(-CHO) groups
Cyclic or Aromatic Aldehydes - Answer-Stem from benzene
Monoaldehydes methanal/formaldehyde - Answer-•Molecular formula CH2O
•Line Formula is HCHO
Formaldehyde structural formula is - Answer-
Methanol is prepared by the partial Oxidation of - Answer-Methyl alcohol/methanol
Properties of methanal/formaldehyde - Answer-•a colorless gas with an
irritating/suffocating Oder
•Soluble in Water
•Readily oxidized to formic acid/Methanoic acid
•It reacts with ammonia to form urotropin/
Methenanime
Urotropin is the neutralization product of - Answer-Formaldehyde by ammonia
What is the formula for urotropin - Answer-C6H12N4
6HCHO + 4NH3 —> - Answer-C6H12N4 + 6H2O
Ammonia neutralizes the formaldehyde and forms urotropin which will not - Answer-
Preserve the protein of the body
Ammonia is present in the corpse due to the breakdown of nitrogenus compounds. The
more ammonia that is present, the more: - Answer-Neutralization of Formaldehyde
there will be and the less preservation will occur
The greater the amount of decomposition; or the amount of ammonia will be present in
the body; the greater the - Answer-Formaldehyde demand will be due to the
neutralization of formaldehyde; so the greater the index you will need to use
Formaldehyde demand - Answer-that amount of formaldehyde necessary to overcome
any nitrogen residue thus resulting in Preservation
Formaldehyde has a tendency to polymerize to - Answer-Paraform/ParaformAldehyde
