(a)[4]
For each technique, state the sub-atomic particle involved, and explain how that particle interacts with the radiation.
(b)
NMR spectra 1 and 2 were recorded before and after alcohol Y was oxidised to form compound Z.
(b(i))
State which spectrum, 1 or 2, was produced by the alcohol, and give a reason for your choice.
(b(ii))
The mass spectrum for Y gave an $M : M+1$ peak ratio of $17.6 : 0.6$. Use this, together with the other information in the question, to propose the identities of both Y and Z.
(b(iii))
In the box provided, draw the displayed formula of $Y$.
(b(iv))
Explain why the NMR spectrum of $Z$ displays only one peak.
