NH3 is the nucleophile because it has a lone pair which "attacks" the electron deficient centre.
How about the chlorine that replaces the hydrogen in the first step. what mechanism is that ?

That is free radical substitution.
Can you help me in this ? in the mark scheme, it's written the concentration of the complex is 0.1. Shouldn't it be 0.1 minus the concentration of c(i) ?

What we require here is a tertiary alcohol with a chiral carbon. You can check by drawing that 5 and 6 carbons will not give you a chiral carbon along with a tertiary alcohol. So 7 is the minimum number. The structure will be:
CH3CH2C(OH)(CH3)CH2CH2CH3
7.1 x 10^-7

1. It has to be a tertiary alcohol, as it cannot be oxidised.
2. It is chiral, so it has 4 different groups attached to the main C atom.

Here you go. It would be a really crowded structure in a space fill model.

Are we required to know this? I've never heard of EDTA :/Here you go. It would be a really crowded structure in a space fill model.

No, don't worry, I do not think you need to know it for A-levels. I just answered since I studied about it in biochemistry.
Just for general knowledge, EDTA stands for Ethylene-Diamine-tetra-Aceticacid and is either used as an anticoagulent (prevents blood clots) for preserving blood specimens or as a chelating agent that binds calcium with other metals.

Ah I see! Thank youNo, don't worry, I do not think you need to know it for A-levels. I just answered since I studied about it in biochemistry.

Whatever is not absorbed is the color of the substance.
For C, 650nm is least absorbed so color is red.
For D, 450nm is least absorbed so it's blue.
Isn't it 400 for D ?
