addition reactions to alkenes

Haloalkanes can be prepared by the addition of halogen acids (HBr, HCl or HI). In the addition of halogen acids to unsymmetrical alkenes, Markownikoff's rule is followed in which 'the negative part of the attacking reagent attaches itself to the carbon atom carryi..

Reactions in which two molecules react to form a single product are called addition reactions. For example, Depending upon the type of attacking reagent, the substitution or addition reactions are also classified as free radical, electrophilic ..

Carbon-carbon triple bond, C=C, is a combination of one and two bonds. Alkynes give electrophilic addition reactions as they show reactivity due to the presence of bonds. This property is similar to alkenes but alkynes are less reactive than alkenes towards ..

Alkenes are more reactive than alkanes due to the presence of a double bond. The carbon-carbon double bond consists of a strong bond and a weak p bond. The typical reactions of alkenes involve the breaking of this weaker p bond, viz., and formation of two sigma ( ..

Benzene gives some addition reactions. Some typical reactions ar..

="left"> They are insoluble in water and soluble in benzene, alcohol, acetone and ether. Combustion They undergo complete combustion production CO 2 , H 2 O and heat. They burn with a sooty flame because of the higher percentage of carbon in them producing CO 2 H 2 O and heat. They burn with a soot..

When the molecules of same monomer or different monomers simply add together to form a polymer,the process is called addition polymerization. The monomers commonly used are unsaturated compounds such as alkenes, alkadienes and their derivatives. This mode of polymerization can t..

Alkenes react with halogens to form dihaloalkanes. The order of reactivity is, chlorine > bromine > iodine. Simply mixing together the two reactants, usually in an inert solvent like carbon tetrachloride, best carries out the reaction. Alkene ..
