The IUPAC name of CH₃CH₂CH₂CH₂CH(OH)CN is 2-Hydroxyhexanenitrile as its carbon chain is 6 carbons long (Hex). The nitrile group takes naming priority over the a...

In 100g of compound, the amount of each element is given by: C: n = 52.2/12 = 4.35 H: n = 9.3/1 = 9.3 N: n = 8.7/14 = 0.621... O: n = 29.8/16 = 1.8625 Dividing through by the smallest amount (0.621) gives...

Bonding is about the movement of electrons-electrons are NEGATIVELY charged-the electrons move to allow atoms to become more STABLE by having a full outer shell of electrons-The periodic table is useful t...

As the question is 2 marks, show working to ensure you get a mark even if answer is slightly wrongFrom periodic table you can see that the relative atomic masses are oxygen = 16; aluminium = 27; sulfur = ...

The reactivity of group 1 metals increases as you go down the group. This is due the number of electron shells increasing, leading to the distance between the outermost electron and the nucleus. The incre...
