Alkyl groups- Alkyl group is formed by removing a hydrogen atom from the molecule of alkane. Alkanes are quite often represented as R-H and here R stands for alkyl group. To learn more about Nomenclature, Types, Formation, Alkyl cation, anion, radicals a
Intercage hydrogen-bonds and hydrophobic interactions between-butyl groups direct the hierarchical assembly of the cages into a permanent porous material. The chiral phosphoric acid-containing frameworks can be high efficient and recyclable heterogeneous Brnsted acid catalysts for asymmetric [3+2] coupling...
How inclusion of additives affect silicone rubbers? Silicone rubbers generally contain additives to obtain high performance for a desired application. Crosslinking- Silicone rubbers are cured/crosslinking either by: Peroxide crosslinkers (benzoyl peroxide, 2,4-dichlorobenzoyl peroxide, t-butyl perbenzoate...
