Stereochem

[The8]

Can you guys look at the attached screenshot and assign carbon 2 stereochem and carbon 3 stereochem and provide a method for how you did so.... I keep getting S and R respectively but that is apparently wrong.

I got 2S, 3R as well

2S, 3R here too. Weird. Even with the double bond rule, N has a higher atomic number than C and should have priority.

I also got 2S, 3R. Where is that structure from?

NextStep said that so probably a typo.. what bond rule are you talking about @confidentandgood ?

It's 2S 3R. If it says anything different, then it's a wrong answer.
