In Reimer Tiemann reaction of phenol with CCl4 to from the trichloromethane derivative what is the electrophile or the mechanism?
In Reimer- Tieman reaction the electrophile is dichlorocarbene
What is the chemical reaction between iron and 15 M HNO3?
15M nitric acid (HNO3) is a concentrated acid. In a reaction between iron and concentrated nitric acid, iron (III) nitrate [Fe(NO3)3], nitrogen dioxide (NO2), and water (H2O) are produced. The balanced reaction is as follows: Fe + 6HNO3 --> Fe(NO3)3 + 3NO2 + 3H2O
Why do not aliphatic amines give coupling reaction?
because aliphatic amine is a weak electrophile. second because the coupling reaction occur at ortho and para position only,while in aliphatic,there is no ortho or para position
Where does the oxygen produced in the dark reaction of photosynthesis come from?
It is obtained from air. Oxygen is not is not produced in dark reaction but in light reaction
When heat is produced in a reaction what kind of reaction is this?
exothermic
In Reimer Tiemann reaction of phenol with CCl4 to from the trichloromethane derivative what is the electrophile or the mechanism?
In Reimer- Tieman reaction the electrophile is dichlorocarbene
What is electrophilic addition reaction?
The Electrophilic Addition Reaction is when the attacking species during the addition reaction is"Electrophile", it is called "electrophilic addition reaction". Examine: (+) (-) (+) (-) (+) (-) CH2Br-CH2BràH2C-CH2+BrBr-àH2C=CH2+Br2-
Why halogens act both as an electrophile and nucleophile?
depending upon the reaction conditions halogens act as electrophiles,nucleophiles and freeradicals
What is electrophillic?
An electrophile is any an agent that is attracted to electrons. The electrophiles stimulate a chemical reaction by bonding with a nucleophile, creating an electron pair.

How will you convert phenol to 246 trinitrophenol?
very easy, a single step reaction. When phenol is heated with Concentrated Nitric acid 2,4.6-trinitrophenol (Picric acid) is produced.
Why was a concentrated solution used if there was no reaction with the dilute solution?
Because concentrated solution has more acidic particles as compared to dilute acid, so when there is no reaction with dilute acid then we use the concentrated acid.
Why do not aliphatic amines give coupling reaction?
because aliphatic amine is a weak electrophile. second because the coupling reaction occur at ortho and para position only,while in aliphatic,there is no ortho or para position
Why in pyrrole substitution reaction occur preferably at 2 and 5 positions?
when an electrophile attacks at 2 or 5 position we get an intermediate in which + charge is on the ring but when the attack is on 3 or 4 position the + charge get on nitrogen atom which is the strongly electronegative in the ring and get destabilised. and hence the electrophile prefer to attack on 2 or 5 position
What is often produced during a chemical reaction?
If the reaction is exothermic then heat is produced.
What are elements or compounds produced by a chemical reaction?
products are produced after a chemical reaction.
What would be observed if concentrated hydrochloric acid were added to silver nitric acid solution?
a white solid precipitate would form with heat being produced since the reaction occurring is exothermic
