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...

Types of reaction intermediates in organic chemistry

Intermediate is an unstable compound formed during a chemical reaction . This intermediate is very unstable and get converted  into product as soon as it forms . Reaction intermediate forms in one step of a chemical reaction and get converted into product in the next step .  There are basically four types of reaction intermediates in organic chemistry ◆Carbocation ◆carbanion ◆free radical ◆carbene Carbocation Carbocation is an intermediate in which  carbon atom carries a positive charge . Carbocation is obtained during heterolytic fission.  Heterolytic fission is defined as break down of covalent bond in such a way that more electronegative atom attract  both the electrons . Carbocation is formed when more electronegative atom is directly attached to carbon atom during fission . Carbocations are sp2 hybridized having trigonal planar geometry Stability of carbocation depends on how easily electron density of carbocation can be increased . More the electron donati...
