what happens when x's bromine reacts with benzothiophene in chloroform at r.t. I think initially it should add to 3- position ( sigma-complex more stable for 3-position than 2- position ) .I think the 2nd eqv. should add to 5- position , but I'm not sure.

x's 
r.t.
eqv.

Seems perfectly clear, imho.

x's = excess
r. t. = room temperature
eqv. = equivalents


Check Section 21.1.1 in John A. Joule & Keith Mills, "Heterocyclic Chemistry", 5th Edition, 2010, Wiley:New York to see what they have to say about reacting benzothiophene with Br₂ and their suggestion concerning a better way to prepare 3-benzothiophene.

Then, you might check their suggestion regarding the structure of the corresponding dibromobenzothiophene.
