Question

1. What is an "organic" chemical? What are the two most important elements that are present in organic chemicals?

2. In addition to the two elements specified in Question #1, name four other very important elements that are present in living systems and organic chemicals.

3. Define (what is the distinguishing feature?) and give a common example for each of the important organic chemical families. What is their main purpose in society (or what is your example used for), and what are the important environmental considerations, if any?

a) alkanes e) alcohols g) organophosphates

b) alkenes f) ethers h) amines

c) alkynes g) aldehydes

d) aromatic compounds f) organohalides

4. What is a polymer? Give an example of one.

5. Which type of organic compounds is used as fuels?

6. Name one family of organic compounds that have been used extensively as solvents.

7. Give an example of a potential environmental problem associated with polymers. Give an example of a solution to an environmental problem that utilizes polymers.

8. Which of the following organic families of compound is the least toxic? (a) alcohols (c) alkanes (e) amines (b) organohalides (d) aromatics (f) aldehydes

Answer 1

1)THE organic componds are the compounds which contain carbon and hydrogen as the main constituent . the 2 elements are carbon and hydrogen

2)nitogen,oxygen,phosphorus,iron

3)alkane are the saturated hydrocarbon .eg= methane,ethane , alkene are the unsaturated hydrocarbon. eg=ethene ,alkynes are the highest degree unsaturated hydrocarbon. eg=acetylene. it is used as welding fuel .

4)the repeating unit formed by condensation of the monomer or simply linking to an another monomer is called polymer. eg = dacron,PVC

5)ALKANES ARE used as fuels

6) alkyl halides

7)polymer like polyethene are non biodegrable hence causes pollution.using biodegradable polymer eg =PHBV

8) C) ALCOHOL
