# Stereochemistry + isomer check

[Please imagine green bonds as dotted bonds going into the plane]

From compound M, we are told that the 3 membered ring is opened u using sodium azide yielding a mix of isomers N and O.

I drew the following:

and

[Again, please imagine the green bonds as dotted bonds and the blue bonds as wedge bonds]

Given are the following two molecules:

Are my solutions the same as the ones given? If they aren't, where did I go wrong?

Many thanks!

• Your solutions are not the same. You have not considered atttack by azide on the epoxide next to the ether. – Waylander Jan 4 at 11:48

Now if I assume that you have mistakenly skipped the O atom in your both products, then your first molecule matches with the first answer given below. But  the second answer given by you is not correct and doesn't match with the second answer. You can have the green and blue coloured bond in the same place and then you have to alternate the position of OH group and azide group. Then that will match the answer given below and the answer will be correct.
