AI Thread Summary
The discussion focuses on identifying β-naphthol through a dye test using various solutions: dichloromethane, acidic, neutral, and alkaline. Participants explore the relationship between dye properties and the pH of the solutions, questioning how to determine if a dye is acidic or basic. The mechanism of phenyl ring activation by a positively charged diazo compound is considered in relation to its reaction with nucleophilic phenyl rings. Understanding these interactions is crucial for accurately identifying β-naphthol. The conversation emphasizes the importance of the dye's chemical behavior in the identification process.

Homework Statement


For the identification of β-naphthol using dye test, it is necessary to use
1. dichloromethane solution of β-naphthol
2. acidic solution of β-naphthol.
3. neutral solution of β-naphthol.
4. alkaline solution of β-naphthol.

Homework Equations


NA

The Attempt at a Solution


There must be a reason which we can apply anywhere not for this question only.
There is something to do with dye but dye is a colour or an Azo compound.
How can we tell dye is basic or acidic?
If we know that also then how to identify the given naphthol?
 
Think about the mechanism for phenyl ring activation. How will a positively charged diazo compound react with a nucleophillic phenyl ring?
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
