The outer or valence shell of these elements is complete. And they need not to make any bond. They do not share or transfer the electrons . Due to fully filled orbitals, Their ionisation enthalpies are also very high. So removing an electron from them is also very difficult. The examples of these are Helium,Continue reading “Why are the noble gases chemically inert?”

What is the decreasing reactivity order of halogen hydracids (HCl, HI, HBr) for addition reaction of alkenes? Explain.
The decreasing order of reactivity will be as follows:- HI > HBr > HCl In case of reactivity the HI will be the most reactive and then HBr and least reactive will be the HCl. This is due to the fact that the reducing character of Iodine is highest and it can easily break theContinue reading “What is the decreasing reactivity order of halogen hydracids (HCl, HI, HBr) for addition reaction of alkenes?
