A hydrohalogenation reaction is the electrophilic addition of hydrogen halides like hydrogen chloride or hydrogen bromide to alkenes to yield the corresponding haloalkanes. [ 1 ] [ 2 ] [ 3 ] If the two carbon atoms at the double bond are linked to a different number of hydrogen atoms, the halogen is found preferentially at the carbon with fewer ...

Fox News Digital spoke to an egg expert based in Maine to find out why egg yolks come in different colors — and if these different colors mean anything significant in terms of nutrition.
Example of hydrohalogenation: addition of HBr to an alkene. Hydrohalogenation involves addition of H−X to unsaturated hydrocarbons. This reaction results in new C−H and C−X σ bonds. The formation of the intermediate carbocation is selective and follows Markovnikov's rule. The hydrohalogenation of alkene will result in haloalkane. The ...
The addition of front-of-label nutrition facts would mark the first substantial change to food labeling in that time. However, it is hardly the first time state and federal governments have ...
