Classification of Organic Compounds Based on Structure

Leave a Comment / Uncategorized

Classification of Organic Compounds Organic compounds are hydrocarbons and its derivatives. Due to the unique properties of organic compounds that carbon is not only linked with carbon but also with other elements like nitrogen, oxygen, sulphur etc to form a long chain or ring compounds. Therefore, organic compounds are in millions. To study organic compounds …

Methods of Preparation of Alkynes – Organic Chemistry Notes

Leave a Comment / Uncategorized

General Methods of Preparation of Alkynes: By dehydrohalogenation of vicinal dihaloalkanes: The removal of hydrogen and halogen is called dehydrohalogenation. When vicinal dihalides are heated with an alcoholic solution of KOH,  hydrogen and halogen atoms are removed from adjacent carbons and in two steps alkynes are produced. Dehalogenation of Tetrahaloalkanes: Tetrahaloalkanes on treated with active …

Alkyne Nomenclature | Common vs IUPAC System – Organic Chemistry

Leave a Comment / Uncategorized

Alkynes Alkynes are unsaturated hydrocarbons which have at least one carbon-carbon triple bond and a general molecular formula CnH2n-2.  Their functional group is – C ≡ C –. Alkyne Nomenclature: Common System: In the common system, alkynes are considered alkyl derivatives of acetylene (the smallest member of the family). First names of alkyl groups present …

Why alkenes are more reactive than alkanes – Hydrocarbons Notes

Leave a Comment / hydrocarbons

Reactivity of alkenes:   Alkenes are more reactive than alkanes. Reason !! Alkenes have a double bond which consists of a strong sigma (δ) bond (bond energy = 83 Kcal/mol) and a weak pi (π )-bond (bond energy = 63 Kcal/mol). The density of π-electrons is high above and below the bond axis. In other …

Explain the Relative Stability of Alkenes – Hydrocarbons Notes

Leave a Comment / hydrocarbons

Relative Stability of Alkenes: Various alkenes differ in stability. The extent of stability of alkenes depends upon following factors: Position of double bond:  1-Butene is less stable than 2-butene which is evident from their heats of combustions. 1-butene being least stable liberates more heat on combustion. CH2 = CH – CH2 – CH3 + 6O2 …
