WebWell atoms like cesium or francium have very small electronegativity values. And so pairing them with the electronegative atoms commonly associated with hydrogen bonding (nitrogen, oxygen, and fluorine) will have a large enough electronegativity difference that their bonding is no longer considered polar covalent, but rather ionic.
Cisplatin 12. Modes of Action of Cisplatin - Chemistry …
WebCisplatin is an alkylating agent that prevents DNA replication in cells. It consists of two ammonia ligands and two chloride ligands bonded to a central platinum ion. Cisplatin works by bonding to nitrogen atoms in the base guanine using a ligand substitution reaction. This damages the cell's DNA, prevents DNA replication and triggers cellular ...

WebIn the cisplatin molecule, the atoms H, Cl, N, and Pt are involved in bonds. H is bonded with N, Pt is bonded with B, and Pt is bonded with Cl. The eletronegativity values for these atoms are as follows: hydrogen (H) is 2.2, nitrogen (N) is 3, platinum (Pt) is 2.3, and Chlorine (Cl) in 3.2. WebThe bonds between their monomers are broken, via the donation of a molecule of water, which contributes a hydrogen atom to one monomer and a hydroxyl group to the other. Carbohydrates The term carbohydrate means “hydrated carbon.” Recall that the root hydro- indicates water. WebJan 30, 2024 · The ionization energy of molecular nitrogen is 1503 kJ mol -1, and that of atomic nitrogen is 1402 kJ mol -1. Once again, the energy of the electrons in molecular nitrogen is lower than that of the electrons in the separated atoms, so the molecule is bound. As a third example, consider fluorine, F 2. pm kisan samman nidhi me e kyc kaise kare
