BeCl2 has a linear shape with a bond angle of 180 degrees, where as H2O has a bent shape with a bond angle of 104.5 degrees. Explain why these molecules have different shapes despite having the same general formula of AB2.

BeCl2 contains 2 bonding pairs of electrons which arrange themselves as far away as possible to minimise the electron repulsion between them, giving a bond angle of 180 degrees and a linear shape. H2O also h...

A batch of Titanium(iv) Chloride is electrolysed in a chemical plant. (a) State the type of bonding in Titanium(iv) Chloride and why it has to be molten in order to undergo electrolysis. (b) Explain why a DC current has to be be used for electrolysis.

(a) Ionic bonding. Ions are free to move/flow(b) So only one product is produced at each electrode OR So that the cathode/anode stays negative/positive which allows only the positive/negative ions to reach t...

Explain the trend in boiling points for the group 6 hydrides (O,S,Se,Te). Diagram would be included.

There are 2 factors that affect this problem. (1) The hydrogen bonding ability of H 2 O which increases the boiling point.The partial charges, induced by the higher electronegativity of oxygen, mean that the...

Why does propanol have a higher boiling point than propanone, propanal or methyl ethanoate?

Molecules of propanol have a hydrogen directly bonded to a NOF atom (oxygen in this case), which means that they can hydrogen bond with eachother. The oxygen in the other three molecules is only bonded to a ...

How is the bonding in NH3 and what does this entail for its electron-domain geometry and molecular geometry?

Nitrogen has atomic number 7; so, when neutral, it has 7 electrons . Those electrons are organized according to the Aufbau principle in an electronic configuration of 1s 2 2s 2 2p 3 . That means there are 5 ...
