7. (0) An unknown molecule Y has a molecular formula of CsH1002, a broad absorption in its IR spectrum from 3200 to 3550 cm region, and no absorption in the 1620 to 1780 cm region. No carbon atom in the structure Y has more than one oxygen atom bonded to it and Y can exist in two (and only two) stereoisomeric forms. What are the structures of these forms of Y?

Question! ID An unknown molecule Y has a molecul Gho, a broad absorption for its IR. Spectrum from 3200 to 3550 cm region, and no absorption in the 1626 to 17 80cm-l region. No Carbon atom in the Structure Y has more than one oxygen atom bonded to it and Y can exist in two (and only two) Sterzo isomeric forms, What are the structences of these forms of Y? formula 402 So, dorable bond equivalent Said px - Halogen like, D.B.B = C+ /-/+ 1/2 L df, Br] or, Tc-Carbon or any tetravalent 2 c-H+ N +2 0 atom, 2 H. Hydrogen or any monovalentatom Na Nitrogen or any trivalent atom N according to this, 2 x $ - 10+0+2 - % 2 1 5xplanation: therefore there is either a double bond or ring present. i) As there is no absorption ist 1620 ml – 17 gou region", here is no carbonyl or > C=ck (alkene grp) presents in the moleulle, 11 Therefore only porsesents presence of a sing is possible in) Again from IR data shows 3200 to 3550 cm region which suggests one or two (0) bond and it's possibly intra moleculare (-or) bond present.

possible Stors are. ( ["As is in B-face] popole and also possible I Str. are. 24 он OH (cis) non cerround) Since the last pair is a diastersomeriz Dair so fowe possible Streo isomer are there. " But according two question only two Stereo - isomers are possible As First pair es enantiomeric pair. only two stereo isomers are possible, so the possible str. are chor & Dunch-on.
