Chapter 1, Problem 1.68P

(a)

Interpretation Introduction

Interpretation:

The average mass from each set of data is to be calculated. Also, the most accurate one is to be identified.

Concept introduction:

Precision is defined as the closeness of two measurements with each other. Accuracy refers to the closeness of the measured values to the standard or known value. Some errors also occur in the calculation of the measured quantities.

The two types of errors are as follows:

1. Systematic error: This error is a part of the experimental setup or faulty devices.

2. Random error: This error occurs always and is due to instruments’ precision.

Average mass is calculated by the sum of all the masses divided by the number of masses.

(b)

Interpretation Introduction

Interpretation:

The most precise data is to be identified. Also, whether the most precise data is equal to the most accurate data or not is to be determined.

Interpretation Introduction

Interpretation:

The most accurate and the most precise data is to be identified.

Concept introduction:

Precision is defined as the closeness of two measurements with each other. Accuracy refers to the closeness of the measured values to the standard or known value. Some errors also occur in the calculation of the measured quantities.

The two types of errors are as follows:

1. Systematic error: This error is a part of the experimental setup or faulty devices.

2. Random error: This error occurs always and is due to instruments’ precision.

Precision is estimated by the range of the data. The formula to calculate the range is as follows:

  Range=(Largest value)(smallest value)        (2)

Interpretation Introduction

Interpretation:

The least accurate and the least precise is to be identified.

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
In the drawing area below, draw the major products of this organic reaction: 1. NaOH ? 2. CH3Br If there are no major products, because nothing much will happen to the reactant under these reaction conditions, check the box under the drawing area instead. No reaction. Click and drag to start drawing a structure. ☐ : A ค
Predict the major products of the following organic reaction: NC Δ ? Some important Notes: • Draw the major product, or products, of the reaction in the drawing area below. • If there aren't any products, because no reaction will take place, check the box below the drawing area instead. • Be sure to draw bonds carefully to show important geometric relationships between substituents. Note: if your answer contains a complicated ring structure, you must use one of the molecular fragment stamps (available in the menu at right) to enter the ring structure. You can add any substituents using the pencil tool in the usual way. Click and drag to start drawing a structure. Х а
