Benzene consists of a ring of 6 carbon molecules. Each of these carbon molecules are bonded to each other by single bonds. This leaves free electrons in p-orbitals. The p-orbitals overlap, creating pi-bon...

The element carbon can exist as a few different "isotopes" - all this means is that the number of neutrons in the nucleus can vary to give atoms that behave the same way chemically so are still ...

Group 5 and 6 have a different electronic structure, with group 6 having one extra electron that group 5.

If we look at Hunds rule, which states that electrons must occupy orbitals individually bef...

pH is calculated using the equation pH=-log[H+]. The concentration of H+ ions, therefore, needs to be calculated. The amount of each substance can be calculated by multiplying the concentration by the vol...

Phenylamine is a weaker base than ethylamine because the lone pair on the nitrogen atom in phenylamine is spread into the delocalised electron ring in benzene, therefore is less available for protonation ...
