Am I going crazy or is that compound not naphthalene? Its anthracene right so it would have 3 monobrominated compounds.

maybe post a pic of the question and you will get some responses.

Ask and you shall receive.

I think you're right... I forgot but somewhere in destroyer there's a similar question too.

Edit: Actually just found it lol; it's question 3 in destroyer and holy crap it's pretty much the same exact question.

YES!!! You're right! I just took that today and was thinking the same thing....in Destroyer napthalene is a 2 ring compound (I looked it up online to be sure...)

 

[emminent]

Lol I wonder who took from who... Jk. But the answer is 3 too on the sample test right?

 

[mjmjmjmj]

I think it was two actually...can't quite remember though

 

[emminent]

They probably referred it to naphthalene then put the wrong picture then 😛

You need to google errors for both sample ADA tests you take. You'll find the posts hidden somewhere deep in SDN, so just type it in google. Also look for errors if you happen by any chance to download the few achiever practice tests floating around the internet. They have a lot of errors too.

For number 81 in the O Chem section, isn't a carboxylic acid with an Iodine attached more acidic than one with a Fluorine? i dont see how F is stronger than I but thats what they have in the answer key!

Inductive effects. Halogens are EWGs and the more electronegative the atom, the more acidic
