This set of operations define the point group of the molecule. 25(11) , 1870-81, (2014). Specification Sheet FT-IR Condensed Phase. Chlorobenzene. Dichlorobenzene, any of three isomeric organohalogen compounds known as 1,2-, 1,3-, or 1,4-dichlorobenzene (also called ortho-, meta-, and para-dichlorobenzene, respectively).Both 1,2- and 1,3-dichlorobenzene are liquids. endstream endobj startxref Due to chlorine donating its lone pair of electrons to the resonance in benzene ring, the ortho and para posns become negatively charged and hence chloro benzene is said to be ortho/para directing group. The use of DDT in agriculture was banned in the 1970's, after its acute toxicity to humans and implications in breast cancer became concerns. endstream endobj 16 0 obj <> endobj 17 0 obj <>/Border[0 0 0]/Rect[334.724 507.352 351.724 522.352]/Subtype/Link/Type/Annot>><>/Border[0 0 0]/Rect[79 109 95 124]/Subtype/Link/Type/Annot>><>/Border[0 0 0]/Rect[248 109 292 124]/Subtype/Link/Type/Annot>>]/Contents[20 0 R 22 0 R 23 0 R 24 0 R 25 0 R 26 0 R 27 0 R 28 0 R]/CropBox[0 0 612 792]/MediaBox[0 0 612 792]/Parent 13 0 R/Resources<>/Font<>/ProcSet[/PDF/Text]>>/Rotate 0/Type/Page>> endobj 18 0 obj <>stream EINECS 203-575-8.
