The kinetic energy should be calculated in the given statement by using the equation of kinetic energy. Concept Introduction: Energy is the ability to do work or transfer heat where work is the movement of a body using some force. The SI unit of energy is joule (J). Energy can be in the form of kinetic energy or potential energy. Kinetic energy is the energy associated with motion. One of the forms of kinetic energy is thermal energy. Kinetic energy (in joule) is calculated using the formulae: E k = 1 2 mv 2 Where, m- Mass in kilograms v- Velocity in meters per second. Thermal energy is the internal energy of an object due to the kinetic energy of its atoms and/or molecules. The atoms and/or molecules of a hotter object have greater kinetic energy than those of a colder one, in the form of vibrational, rotational or, in the case of a gas, translational motion. For example, a hot brick has a greater kinetic energy than a cold brick.

Interpretation Introduction

Interpretation:

The kinetic energy should be calculated in the given statement by using the equation of kinetic energy.

Concept Introduction:

Energy is the ability to do work or transfer heat where work is the movement of a body using some force. The SI unit of energy is joule (J). Energy can be in the form of kinetic energy or potential energy. Kinetic energy is the energy associated with motion. One of the forms of kinetic energy is thermal energy. Kinetic energy (in joule) is calculated using the formulae:

Ek=12mv2

Where,

m- Mass in kilograms

v- Velocity in meters per second.

Thermal energy is the internal energy of an object due to the kinetic energy of its atoms and/or molecules. The atoms and/or molecules of a hotter object have greater kinetic energy than those of a colder one, in the form of vibrational, rotational or, in the case of a gas, translational motion. For example, a hot brick has a greater kinetic energy than a cold brick.

Q1: For each molecule, assign each stereocenter as R or S. Circle the meso compounds. Label each compound as chiral or achiral. OH HO CI Br H CI CI Br CI CI Xf x f g Br D OH Br Br H₂N R. IN Ill I -N S OMe D II H CO₂H 1/111 DuckDuckG

These are synthesis questions. You need to show how the starting material can be converted into the product(s) shown. You may use any reactions we have learned. Show all the reagents you need. Show each molecule synthesized along the way and be sure to pay attention to the regiochemistry and stereochemistry preferences for each reaction. If a racemic molecule is made along the way, you need to draw both enantiomers and label the mixture as "racemic". All of the carbon atoms of the products must come from the starting material! ? H H

Q5: Draw every stereoisomer for 1-bromo-2-chloro-1,2-difluorocyclopentane. Clearly show stereochemistry by drawing the wedge-and-dashed bonds. Describe the relationship between each pair of the stereoisomers you have drawn.
