The reactivity of halogens :- The above order in case of halogens is due to the fact that the size of fluorine is small which makes a strong bond with carbon of alkyl group, thus makes it difficult to break. But on the other hand in case of Iodine the bond between Iodine and CarbonContinue reading “What is the order of reactivity of halogen and alkyl groups in the dehydrohalogenation of alkyl halides to give alkenes ?”

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?

What are the chemical properties of Carboxylic Acids ?
What are the methods of preparation of Carboxylic Acids ?
Carboxylic acids are prepared by various methods like oxidation of primary alcohols, oxidation of aldehydes and ketones, hydrolysis of nitriles, grignard reagents, hydrolysis of esters etc.
WHY THE IONIC REACTIONS ARE FASTER?
How are reactions related to chemical bonds? The type of bond has a great effect on the rate of reaction or speed of reaction. Here we are going to discuss why and how it happens, First of all in case of ionic compounds:- Lets take example of Sodium hydroxide and Hydrochloric acid NaOH (aq) +Continue reading “WHY THE IONIC REACTIONS ARE FASTER?”
Why Alkynes are less reactive than alkenes and alkanes towards electrophilic addition reaction ?
There are two reasons for less reactivity of Alkynes towards electrophillic addition reactions:- Due to greater electronegativity of sp-hybridized carbon atoms of a triple bond than sp2 -hybridized carbon atoms of a double bond, pie-electrons of alkynes are more tightly held by the carbon atoms than pie electrons of alkenes and hence are less easilyContinue reading “Why Alkynes are less reactive than alkenes and alkanes towards electrophilic addition reaction ?”
