Okay, problem 33, we are given the structure for vitamin c, and we're asked to figure out, is this going to have a d configuration or l configuration, okay? so by now you probably know some kind of a shortcut, but i would like to just go over the official, official or power way of figuring this out.
00:24
First, we assign r or s configuration, right? so in order of priority of this chiral center okay so looking at the bonds that it has we see that this alcohol group of course has an o so this is going to be our priority one and subsequently we're comparing this carbon to this carbon okay so this carbon on top would be our priority two and and this would be our priority three, okay? and of course, this hydrogen right here would be priority four.
01:06
So given that order of priority, we have that we're going to have this clockwise direction, right, which means it's, that's the r configuration.
01:20
But we see that this priority for hydrogen is going out of the page, right? since this is a fisher projection...
