Question
Which of these chemicals are Discrete Organic Chemicals?
- Triethyl Phosphate
- Tributyl phosphate
- Phosphoric Acid
- Phosphorous Trichloride
Refer to the information below and pls interpret
scheduled Discrete Organic Chemicals(DOCs) fers to any chemical belonging to the class of chemical compounds consisting Il compounds of carbon except for its oxides, sulfides and metal carbonates y are identifiable by chemical name, structural formula (if known) and mical Abstracts Services (CAS) Registry Number (if assigned) s term does not cover: Dligomers & Polymers, whether or not containing Phosphorus, Sulfur or rine. Chemicals containing only carbon & metal Carbon monoxide & Carbon dioxide as referred in the term "oxides of carbon" in the above definition) Carbon disulfide or Carbonyl sulfide (as referred in the term "sulfides of carbon" in the above definition) Plant sites that exclusively produce hydrocarbons and explosives are excluded from the purview of the NA(CWC), and do not require a NA(CWC) licence re are 2 types of unscheduled DOCs: PSF containing DOCs containing the elements Phosphorus, Sulfur and/or Fluorine Non-PSF containing DOCs that do not contain the elements Phosphorus, Sulfur and/or Fluorine E.g.: Acetone is a non-PSF containing DOCs Carbon dioxide and Calcium carbonate are not DOCs; Fluoromethane is a PSF-containing DOCs.Explanation / Answer
Right answers are :
Triethyl Phosphate and Tributyl Phosphate is a PSF-containing DOCs,but phosphoric acid is not a DOC.
Explaination :
(1) Triethyl Phosphate (C2H5)3PO4 is a tri-ester of ethanol and phosphoric acid and called as phosphoric acid,triethyl ester.The compound containing functional group ester is declared as DOCs ex. acetone, so Triethyl Phosphate is a DOCs and it also contain phosphorus element so it is termed as PSF-containing DOCs.
(2) This reason is simillar for case of Tributyl Phosphate (C4H9)3PO4. It is also a PSF-containing DOCs.
(3) Phosphoric acid H3PO4 does not contain carbon i.e. not a compound of carbon so it is not a DOCs.
