WebPhosphorus trichloride (PCl 3) is a toxic and highly reactive reagent, which, on hydrolysis generates phosphorous acid (H 3 PO 3) and hydrochloric acid, exothermically. 23 It … WebJan 23, 2024 · Replacing -OH by bromine. Rather than using hydrobromic acid,the alcohol is typically treated with a mixture of sodium or potassium bromide and concentrated sulfuric acid. This produces hydrogen bromide, which reacts with the alcohol. The mixture is warmed to distil off the bromoalkane. (2) C H 3 C H 2 O H + H B r → C H 3 C H 2 B r + H 2 O.

PCl3 is important indirectly as a precursor to PCl5, POCl3 and PSCl3, which are used in many applications, including herbicides, insecticides, plasticisers, oil additives, and flame retardants. For example, oxidation of PCl3 gives POCl3, which is used for the manufacture of triphenyl phosphate and tricresyl phosphate, which find application as flame retardants and plasticisers for PVC. They are also used to make insecticides such as diazinon. Phosphonates include the herbici… WebChemistry questions and answers. 47) Which of the following reagents is used in the following reaction?

Count the number of atoms of each element on each side of the equation and verify that all elements and electrons (if there are charges/ions) are balanced. Since there is an equal number of each element in the reactants and products of P4 + 6Cl2 = 4PCl3, the equation is balanced. http://www.cchem.berkeley.edu/rsgrp/SOPs2024/Quenching-WaterReactiveChemicals_Sarpong.pdf refrac horizontal well
