You were absolutely correct when you said that nitrosation takes place. What actually happens is that after nitrosation occurs, concentrated $\ce{HNO3}$ oxidises the nitroso group to form nitrobenzene. Source A Guidebook To Mechanism In Organic Chemistry; Chapter 6, section 6.2;Peter Sykes

From Clayden (Chapter 37 Rearrangements page 976): Intramolecular reactions (including participation of a neighbouring group) that give three-, five-, or six-membered rings are usually faster than intermolecular reactions. It also gives the exact same example as your question: ...

I dare you to find an advanced chemistry textbook that does not contain the topic electrophilic aromatic substitution. Have you found it? name the title.

CIP rules for cyclic substituents are different. See this question for the rules. (The rules are given in the question itself). This will be the hierarchical digraph for the right side of the molecule. The atoms encircled are the ghost atoms. From the digraph one can see why the compound is...

Your generation of electrophile is correct the subsequent primary carbocation formation by the attack of electrophile is incorrect. In my second step, that particular carbocation is formed since $\ce{Ph}$ is an electron-withdrawing group. The benzene ring stabilizes the carbocation th...

Are there any computer programs or online resources that could help me figure out whether the reaction will take place or not, and if yes, at what temperature? Long version of the same question: I am starting to learn chemistry. I found a video "The Laws of Thermodynamics, Entropy, and Gibbs Fre...

Benzene ring with a positive charge. Will the positive charge be delocalized?

On sites like CrossValidated (but I guess this applies also to the math sites etc.) we often have users who post math formulas as pictures, rather then using TeX formatting that is supported by the platform. Some of the users are unfamiliar with TeX, some just lazy, yet it would be nicer to have ...
