Synthesis question on organic chemistry?

Members do not see this ad.

So in my college course (orgo I/2), we have questions on tests where in order to get the product, we have to go through MULTIPLE steps with MULTIPLE reagents in order to get to the final product.

In chad's videos, he goes over every reaction with each of their corresponding reagents, but he doesn't necessarily do any examples where it contains a combination of all these (aka synthesis question).

on the DAT orgo, are there any of these multistep questions that you have to know? or do we just have to know the individual reactions?

There are multistep synthesis questions, yes. Under subsection 5.

It really shouldn't be a big problem though, its just like asking 2-3 individual reactions in a row, nothing new. 🙂

Well, the simple answer: If you know all the individual reactions, you can do all of the multi-step reactions.

They'll be on there, but nothing I saw was terribly difficult. I wouldn't expect anything more than three steps.

There are road map questions on the DAT, not a complete synthesis. You will be asked to complete roadmap questions by supplying products of each reactions or the reagents. Hope this helps.

I took the DAT a few hours ago. There were only 2 or 3 multistep synthesis questions.
