What is hydrogen bond? How does an intermolecular hydrogen bond differ from intramolecular hydrogen bond ?

Actually the hydrogen bond is simply a type of attraction which is caused by the the electronegativity difference between hydrogen and highly electronegative element like oxygen carbon nitrogen and fluorine. Intermolecular hydrogen bonding takes place between two molecules having hydrogen and electronegative element. Hydrogen is attracted by the electronegative element of another molecule for example

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 the

Why isn’t water inflammable? It is made of flammable chemicals which are hydrogen and oxygen.

This is a best example to share when we talk about chemical change, that the products have totally different properties from that of the reactants , from which they are made. Now coming to the answer, Formation of water is a highly exothermic type of reaction and a lot of energy is lost at the
