Question

Folic acid, shown below, is used to treat anemia and as a supplement during pregnancy. How many carbon atoms in folic acid are sp2 hybridized? o OOH 13 O 19 11 15

Answer 1

Aulwer 0 for Hybridization. Calculation use the formula My bri dization i Valence & elections Monovalent - atoms Cation + Anion - - Q IS 2- NY 18 Hņu HN 27 bol ANY 9 2 32 31 214 N. EXAMPLE ③ Take Co. (Carbonyl group) in Red - o has 6 valence electrons v=6 > It has o Monovalent atoms M=0 > No Cationic or Anionic charge C, A=0. So b = vt M-ct A q Hyb= 6 to oto = 6 = 3 = sp².

Similianly a atom of >=o group - c= 4 Valence elections v=4 > c= 2 Monovalent atoms M= 2 > c= c, A (Cationic, Anionic) =o. To Charge Hyb= VTM-CHA - 2 Hyb = 4+2 -0+0 b = 3 = sp . group both c, and o is spa So in , zo hybridized. Similiarly we can calculate the of atoms (other) by following Hybridization same procedure.

So the Hyb. of given atoms (marked with xhumbers as) O o atom of on - sp3 Catom of co-sp² 40 ③ o atom of y yo - sp2 atom → Nalom -NA - ☺ » c atom - sp3 © - Catom - sp3 © > Catom – sp3 ③ [cator iso - spz 4 © -0 atom >=0 – 8pz » oohon ом — sp? 6 Natom of -nn - spå 0 - catom fyzos sp2 + nonton of x souspa 6 fc atom of king sp2 a @ - | Catom of king spz a ② (Catom of Ring 3.sp2 a ® (catom of Ring sp2 4 ☺ te atom g Ring spe a ® [catom of Ring osp2 a ® ☺ 6 ® ③
