(a)

Interpretation Introduction

Interpretation:

The evidence has to be given for the octane rating is not a measure of the energy content of a gasoline.

Concept introduction:

Octane rating or octane number:

It is a measurement of the performance or quality of gasoline. If the octane rating is high, the fuel burns within the engine of a vehicle is better.

(b)

Interpretation Introduction

Interpretation:

The importance of octane ratings in measure a fuel’s ability to minimize or prevent engine knocking has to be explained.

Concept introduction:

Octane rating or octane number:

It is a measurement of the performance or quality of gasoline. If the octane rating is high, the fuel burns within the engine of a vehicle is better.

(c)

Interpretation Introduction

Interpretation:

The reason has to be explained for the higher octane blend is more cost than lower octane.

Concept introduction:

Octane rating or octane number:

It is a measurement of the performance or quality of gasoline. If the octane rating is high, the fuel burns within the engine of a vehicle is better.

(d)

Interpretation Introduction

Interpretation:

The fuel contains oxygenates or not has to be identified when the octane rating of 91 (premium gasoline).

Concept introduction:

Octane rating or octane number:

It is a measurement of the performance or quality of gasoline. If the octane rating is high, the fuel burns within the engine of a vehicle is better.

How many signals do you expect in the H NMR spectrum for this molecule? Br Br Write the answer below. Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H atoms that would contribute to the same signal as the H already highlighted red. Note for advanced students: In this question, any multiplet is counted as one signal. Number of signals in the 'H NMR spectrum. For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in top molecule For the molecule in the bottom drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in bottom molecule
