Question 2: What is the ionic character of NaCl? What kind of bond is it and why?
Induced Dipole = it is an interaction whicch is done between nonpolar species, the "induced" electron electron makes reppeal interacitons, which then "disorders" charges in atoms, which makes them a small dipole. this way they can interact ( london disperison forces)
Ionic = this is a type of interacion which implies ionic electrostaic forces. They need a cation (+ ion) and an anion (-)
Hydrogen Bonding =
Note that for Hydrogen bonding, we must have the next conditions:
- Species is polar, i.e. there are dipole-dipole interactions between the molecules
- There must be an acidic Hydrogen bonded directly to either, N,O,F; which are very electronegative species.
Polar Covalent = covalent bonds are a type of chemical bond due to electron sharing, in poalr covalent bonds, expect unequal share of electrons, therefore, small dipoles are formed in the same bodn
Covalent = covalent bonds are a type of chemical bond due to electron sharing
Metallic = this type of metallic interaciton is present in metals only, the crystal lattice of metals allow electric conductivity
Non-polar covalent = covalent bonds are a type of chemical bond due to electron sharing. In this specific case, the share is equal, so there is no pole formation
Van der Waals = interactions between species in the intermolecular level. They are similar to induced dipoles, interacting between small electrostatic forces
Permanent Dipole = this is a dipole -dipol einteraction, form covalent polar species only.
Question 2: What is the ionic character of NaCl? What kind of bond is it and why?
NaCl is pretty ionic, since Na+ and Cl- are ionic
The main type of force is the IONIC interaction, due to Caiton Anion interaction s(electrostatic forces)
