WebIf you write out the equation for reaction between HNO3 and pentaerithritol you will see that when one mol PE is nitrated four mols H2O are formed. When one mol of glycerin is nitrated three mols H2O are formed. When one mol phenol is nitrated to trinitrophenol three mols water are formed. The same with TNT, and so on.
How does phenol react with Cone. HNO3? Give equation.
WebDilute nitric acid reacts with phenol and produce a mixture of 2-nitrophenol and 4-nitrophenol. With concentrated nitric acid, phenol gives 2,4,6-trinitrophenol as the product. Metals and dilute nitric acid reaction. Dilute nitric acid act as a typical acid when it reacts with a reactive metals such as sodium, magnesium, zinc and more. But ... WebThis can be done by first reating the phenol with $\ce{HNO2}$ Which gives us this . Then reacting with dil $\ce{HNO3}$ we get 90% yield of para nitro phenol . This happens … dz beachhead\u0027s
Reaction of phenol with dilute $HN {O_3}$ givesA. p- and m ...
WebWhen phenol is treated with sodium hydroxide, phenoxide ion is formed. This phenoxide ion formed is highly reactive towards electrophilic substitution reactions. Upon treatment with a weak electrophile (carbon dioxide), it undergoes electrophilic substitution reaction to form Ortho-hydroxybenzoic acid. WebMar 23, 2024 · But the yield of this reaction is very poor. So for enhancing the yield of the reaction phenol is firstly treated with concentrated sulphuric acid which gives phenol$ - 2,4 - $ disulphuric acid and then it is further treated with concentrated nitric acid which produces $2,4,6 - $ trinitrophenol as major product. WebPhenol and dilute HNO 3. A product mixture (ortho and para product) is given as the product. Phenol is an ortho para director. So nitration can be occurred at ortho or para positions with dilute HNO 3 acids. As ortho product, 2-nitrophenol is given. As para product, 4-nitrophenol is given.
