Question

Use the following to answer questions 4-8 Use the following terms to answer the question(s) below. The reaction of molecule A is an example of a(n): neutralization. combustion. oxidation. reduction. condensation. Foods that contain the product of this reaction must be labeled as: hydrogenated or partially hydrogenated fatty oily fat free diet Which of the following choices best describe molecules A and B? Both A and B are fats. Both A and B are oils. A is a fat and B is an oil. A is an oil and B is a fat. A is an oil and B is a trans-fat. What are the best reasons for the descriptions of molecules A and B? Molecules of B are held together by many intermolecular forces, so B melts above room temperature. Molecules of B are not held together very strongly, so B melts below room temperature. Molecules of A are held together by many intermolecular forces, so A melts above room temperature. B contains many trans double bonds. Molecules of B are. Which of the following outcomes is possible as a result of this reaction? A fat is changed into an oil. A solid is changed into a liquid. Additional cis-bonds are formed. A gas is produced. A trans-fat is produced.

Explanation / Answer

Q4.

this is a HYDROGENATION, note that hydrogen addition is a reduction, since oxidation number reduces...

choose D

Q5

foods with this reation must be "saturated" since all double bonds are eliminated

so choose hydrogenated

Q6.

Note that A is likly to be an oil, since it has unsaturated bonds

B is likely to be a fat, since it is pretty saturated

note that an oil is considered a fat

so

bet option is A, both are fats

Q7

B will NOT melt in Room T wheras A will do

so

choose A

Q8

A trans fat migh tb produced in the hydrogenation, so be aware of it, choose E
