Question 1
Paper 2Medium6 marksTwo organic compounds, P and Q, are represented by skeletal formulas in Figure 1.
(a)[2]
State the functional group present in each of P and Q.
(b)[1]
Determine the molecular formula shared by P and Q.
(c)
Use Figure 1 and your answer to (b).
(i)[1]
State whether P and Q are saturated or unsaturated.
(ii)[2]
A student argues that P and Q must belong to the same class of organic compounds because they have the same molecular formula. Explain why this conclusion is not justified.
