What are the hazards of HCL?
Hydrochloric acid is corrosive to the eyes, skin, and mucous membranes. Acute (short-term) inhalation exposure may cause eye, nose, and respiratory tract irritation and inflammation and pulmonary edema in humans.
Why p-nitroaniline is less basic than aniline?
As a result, the availability of the unshared pair of electrons on nitrogen atom in p – nitroaniline is highly reduced as compared to the unshared electron pair on nitrogen in aniline. For this reason, p – nitroaniline behaces as a weaker base compared to anline.
What is the structure of p-nitroaniline?
C6H6N2O2
4-Nitroaniline/Formula

What are the hazardous decomposition products of HCL?
Hazardous decomposition products: Hydrogen chloride, chlorine, hydrogen gas. Polymerization: Hazardous polymerization WILL NOT occur. Information on likely routes of exposure: Inhalation: Vapors and mist will irritate throat and respiratory system and cause coughing.
Why is meta nitroaniline more basic than para nitroaniline?
In the o-nitroaniline and p-nitroaniline compound, delocalization of the lone pair is observed. Therefore, o-nitroaniline is less basic than p-nitroaniline compounds. In m-nitroaniline only inductive effect is observed and therefore, it is more basic compared to others.
How is p-nitroaniline used in dye manufacture?
An Introduction to the Synthesis of p-Nitroaniline via a Multi-Step Sequence. Essential chemical intermediates in dye manufacture are nitroanilines. In this experiment series, p-nitroaniline is synthesized by a multi-step sequence as shown in Figure 1. This compound is used to synthesize the azo dye Para Red.
How to make p-nitroaniline with sulfuric acid?
A 25mL round bottom flask is charged with a solution of concentrated sulfuric acid (4mL) and water (3mL). p-nitroacetanilide (0.7g) is added and heated the reaction mixture gently under reflux for 20min.
How to prepare p-nitroaniline from acetophenone by chemical reaction?
In order to prepare p- nitroaniline from acetophenone, by chemical reactions, one functional group on monosubstituted benzene is transformed into another and then an electrophilic aromatic substitution reaction is done to obtain the target compound. The various compounds prepared will be characterised by 1 H NMR spectroscopy.
What are the two doublets of p-nitroaniline?
The 1 H NMR spectrum of p-nitroacetanilide (Figure 10) shows two doublets at 6.59 and 7.95ppm, corresponding to the four aromatic protons at positions 2 and 3 respectively. The signal for the exchangeable NH2 protons is overlapping with the doublet at 6.59ppm, as indicated by the 2:1 peak integration values.
