The invention relates to a process for hydrogenating carbon-carbon double bonds of an unsaturated polymer by adding to the unsaturated polymer (1) a reducing agent selected from the group comprising hydrazines and hydrazine-releasing compounds, (2) an oxidising compound and (3) a catalyst, ...
A catalyst for hydrogenation of carbon-carbon double bonds, nitro groups and aldehyde groups in aliphatic and aromatic compounds comprises a membrane made from an alloy consisting of 80 to 95% by mass of palladium and 5 to 20% by mass of ruthenium or rhodium and consists of a non-porous la...
The carbon–hydrogen bond is weekend by the presence of this double bond and the hydrogen becomes vulnerable to oxidative attack. Unregulated increase in sperm intracellular ROS aids a progressive reaction cascade inducing LPO (Fig. 2.3).58 As this is a self-propagating autocatalytic reaction, it ...

between hydrogen and carbon atoms of different chloroform molecules, between hydrogen and nitrogen atoms of neighboring ammonia molecules, between repeating subunits in the polymer nylon, and between hydrogen and oxygen in acetylacetone. Many organic molecules are subject to hydrogen bonds. Hydrogen bond:...
Similarly, two carbon atoms can bond with two hydrogen atoms each and form a double covalent bond with each other, sharing their four leftover electrons between them. That compound is ethylene, C2H4. In acetylene, C2H2, the two carbon atoms form a triple covalent bond and a single bond with...
