Here. Question number. Dean. He's How can the falling compounds were prepared from Carbonell compound that has one less carbon than their desired, but it so here a. And we come phone. We have to prepare, starting from the compound, which is having one less carbon than there. Dessert parent. So this starting material for the synthesis of the two carbon must have one carbon. We're starting with a compote. So here in the product to carbon atoms, at present, we have to start with a carbon one carbon atom, and it should be formal de hate. So Etch seen double Bond who h form really hate. And it is treated quickly with at CNN, followed by addition of hydrogen toe, the warned people born and for mission Oh, they required product. So formally Heidi, stricken on it, is treated with, and it's seen sodium Sign eight in presence, off as seat and the product formed. Ease Sino hygiene that is Etch See, It's true seen triple bond, and so in the form of Sino hygiene. One Carbon is interview used in the reactant, and the product should have one more covenant. So in the next step to beat the desired. Brought it to E. We have to do the In addition, off producen in prison, soft raining as get released and the product formed will be, oh oh, parties not disturbed. Then she each drove in in scenes and here at the People bond hydrogen is edit and by the final product will be this component in which one carbonless more and the name off the product is two amino beating. No, now for getting the bigger point. The starting material for the synthesis off this tree carbon compound must have two garments. Therefore, it must be a city. A settled the height addition off at sea and followed by how delicious off the resulting Sino hygiene forms their target. Monk, you so let us see how this phone as it'll behaviors to starting component here. So it should be ch dream, which is having one carbon less than the product. Okay and behaving Cilic date on. After that it is cheated weed sodium sign eight in presence off at shell and by this the product form this siege tree C h seen triple warned and and which group is radically it is to hear. And after that haggle is's dilute a seat mistaken. And for your day, Caijing and the final product will be see each tree C H, which is as such. It is not disturbed. Drancy and group is converted to si or it by this hundreds. And this is the report product. Leave off the product is two hydroxy hi. Drug scene? Probably not. No, I guess it. So in the product, we have one carbon more and that is introduced in the form off CNN in the molecule. So starting compound should have one carbon less than the bullet.
