What kind of bonding occure between these?
2.HCO2Na
3.NaOCH3
4.CH3Li
Answer:
There mainly 2 types of bonds - ionic and covalent. One can distinguish covalent bonding by looking at the electronegativity. Covalent bonding is a common type of bonding, in which the electronegativity between the 2 atoms are similar while ionic refer to those electrostatic interaction due to the large differences in electronegativity.
For your reference electronegativity for the atoms above
Na-0.93 Li-0.98 C-2.55 O-3.44 H-2.20
So in this case,
NaOH - Ionic between Na and OH, covalent for O and H
NaCO2H - Ionic between Na and CO2H, covalent in CO2H, you might like to take note O make the bond polar, and sometimes can be known as polar covalent, an intermediate between covalent and polar
For the next 2 compounds, they are known as organometallic compounds and you can't really group them all together as ionic or covalent. You shd also take note, ionic organometallic is different from ionic compound where it forms crystal lattice. Ionic bond for organometallic only exist within the molecule and often does not form crystal lattice.
NaOCH3 - Ionic between Na and OCH3, covalent and polar covalent in OCH3
CH3Li - Ionic and convalent but more ionic than covalent between Li and CH3. A difference of 1.6 or more is considered ionic, here, it's 1.57 so it's almost ionic but slightly covalent...
Simply, Na always forms ionic bond, Li that has slightly higher electronegativity may form intermediate between ionic and covalent, depending on the type of atoms it bond with.
NaOH is a hydrogen bond
other than that, idk.
1. ionic
2.ionic
3.covalent
4.covalent
