All the carbons in benzene are sp 2 hybridised. The carbons are each bonded to one hydrogen and all bonds to other carbon atoms in the ring are the same length. This bond is in between the bond length of a C...

My best tip for exam preparation is to work your way through the course specification. This gives you the best understanding of exactly what you need to know for the exam, for example all the definitions you...

Non-molecular solids are of the type of metallic and ionic solids. They are held together by the strong electrostatic interactions of polar particles like ions and electrons. For example in metals the strong...

As you descend group 2, more electrons are present in the atom. These electrons fill subshells at a greater energy level. There is a greater distance between the outer shell electron and the nucleus, as well...

Benzene is stable due to its delocalised ring of electrons - which forms as a result of the carbon-carbon bonds being neither single nor double bonds, instead an intermediate length with electrons in the p-o...
