2014年12月14日 · Carbon monoxide (CO) can be viewed as containing one coordinate bond and two "normal" covalent bonds between the carbon atom and the oxygen atom. This highly unusual description illustrates the flexibility of this bonding description. Thus in CO, carbon is the electron acceptor and oxygen is the electron donor.

2015年10月19日 · All we can do is pick out certain cases and attempt to interpret them with our models. Argument in point: even the ionic NaCl bond dissociates homolytically (as mentioned at the end of the answer) much like any covalent bond, proving it is much closer to a covalent bond than to a dative or coordinate bond. $\endgroup$ –

2024年5月19日 · The first thing needed for a dative bond is a lone electron pair in one atom and an empty orbital in another atom. This condition is necessary but enough. There is also a formula for the formal charge $(\mathrm{F.C.})$ that fails in many cases but may sometimes become handy: $$\mathrm{F.C.} = \frac{\mathrm{O.N.} - 8 + \mathrm{G.N.}}{2},$$

2018年12月30日 · $\begingroup$ The difference is that, in coordinate covalent bond the 2 shared electrons are from one atom (O) , while in ordinary covalent bond the 2 shared electrons are from the 2 atoms (one from O, and the other from H) $\endgroup$

The metal-ligand bond is often envisaged as a second type of covalent bond in which we still have a two-centre, two-electron bond, but where both of the electrons come from one of the atoms or from a molecule. This type of bond is known variously as a coordination, a dative covalent or a donor-acceptor bond.

2024年5月20日 · A coordinate covalent bond is a type of covalent bond where one atom contributes both of the shared electrons. In terms of bond strength, coordinate covalent bonds are typically similar in ...

2017年8月17日 · Coordinate Covalent Bonds (a.k.a Dative Bonds): These bonds are just like any other covalent bond. They involve sharing of electrons in between the two atoms that make up the bond. The only difference between a regular covalent bond and a coordinate one is that both the electrons belong to one atom in case of

2024年2月24日 · We know a coordinate bond refers to a covalent bond in which one atom provides a lone pair and the other provides an empty orbital. When OH - gets a proton and becomes H 2 O, O provides a lone electron pair and the proton (H + ) provides an empty orbital; when Na 2 O is dissolved by water, the oxygen ion has a similar change; also when H 2 O ...

2024年5月28日 · The reason why NH3 and H20 can form a coordinate covalent bond with H but CH4 cannot do so is because methane (CH4) only forms single bonds. Hydrogen (H) can form more than one bond.

2013年3月21日 · Coordinate covalent bonds imply the donation of two electrons to a bond with another atom. In the case of $\ce{ SiO2 }$, The structure is actually tetrahedral, with an oxygen between and two silicon atoms, and where each oxygen forms two …
