The changes in reactivity are due to the electron donating/withdrawing properties of the substituted groups. For example the OH group in Phenol is electron donating. This means the electron density of the...

First we must multiply the coefficient of x2 by the value with no x associated with it3x3 = 9Now we must find two numbers that add to make 6 and multiply to make 9+6x9 3 and 3Now we need to split the coef...

Rewrite the equation for L2 to find an equation for y4y=12x-16; y = 3x - 4 2. The x-coefficient gives the gradient (or slope) of the line, so since the gradient of L1 is 3, and as we have just shown, the ...

1^st consider the bonding in methane, CH4. The carbon atom forms 4 single covalent bonds to hydrogen atoms. However, when we consider the electronic configuration of Carbon (electrons-in-box not...

The first step is to create a basic checklist which can be used for any of these types of questions. This could include a few grammar tenses and structures, a few versatile bits of vocabulary, and some po...
