Acidic order of Halogens- hydrogen halides acidc strength

Acids are the substance which can donate  Hydrogen ions in solution or the substance which accept electrons . But now the question is how to know which acid is more acidic and which one is less .    For this you have to understand that Strong acid can easily donate H+ This state is valid for the molecules having Hydrogen atom in their molecules . acidic order/ Strength of halogens ( Hydrogen halides ) Hydrogen halides are the molecules having hydrogen and halide group(Fluorine , Chlorine , Bromine and Iodine ) .Bond length between Hydrogen halides increases down the group due to increase in the size of halide atom .  Increasing order of bond length : HI >HBr >HCl> HF Due to increase in bond length , bond strength become weaker down the group . Order of Bond strength : HF >HCl >HBr> HI It means that Hydrogen Iodide(HI) can easily donate proton ( due to weak bond ) into the solution and therefore it is most acidic hydrogen halide  whereas Flouri...

Why Solids are rigid and incompressible ?

Matter is anything that has a mass and occupy space . Ice  , pen , pencil ,dog , etc are examples of matter because they have some mass and they occupy space . There are basically three states of matter , ●Solid  ●Liquid ●Gas Solid   Solid is defined as rigid and incompressible state of matter .  Now the question is , why Solids are rigid and incompressible ? To answer this question , let's understand the properties of solids .  1.Solids have large intermolecular force of attraction . Intermolecular force is the force of attraction between to adjacent Molecules .  Higher the intermolecular force , more tightly they will attract each other and less movement of Molecules will occur . 2.Intermolecular distance in Solid is very less . Intermolecular distance is the distance between two adjacent molecules . Less the distance more will the intermolecular force of attraction . Intermolecular force is inversely proportional to intermolecular distance . ...
