Why is a water molecule non-linear?

Valence Shell Electron Pair Repulsion Theory (VSEPR) states that lone pairs repel other lone pairs more so than they do bonded pairs. In water, the oxygen atom has two lone pairs. These two lone pairs rep...

Draw an example using a diagram of Carbon, three "Y" substrates and an "L" indicating any leaving group the Sn1 nucleophilic substitution reaction. (3 marks) Which step is fastest (1 mark).

Y₃CL -> [Y₃C]⁺+ L^-(1 mark)Ligand leaves in first step. Can still show ligand as product anion but no need. Also accept any halide as leaving group.
Ste...

What happens to the reactivity going down group 7?

The reactivity decreases down group 7 as the atomic radius increases, as the distance between the outer shell electrons and nucleus increases. As a result less energy is required to remove the outer elect...

What happens when two atoms of potassium react with one atom of sulphur?

Bonding between this compound will be ionic as potassium is a metal and sulphur is a non-metal.Therefore electrons are transferred from potassium to sulphur as metals must lose electrons to gain a full ou...
