I need help with all three problems
EXPERIMENT # 2: ORGANIC STRUCTURES AND MOLECULAR MODELS B. Bond Lengths and Resonance TeGaussian molecular modeling software utilizes the sophisticated Molecular Orbital Theory to predict the optimal geometry of molecules in the gas phase. Techniques used are theoretical predictions rather than experimental results. With the help of your instructor, use the Gaussian program to investigate the bond lengths of ethane (C,He), ethylene (CH), acetylene (C H2), and benzene (C&Ha). In each case build...

3. We have described how acyl chloride compounds (RC=OCI) can, with the assistance of a Lewis acid catalyst, act as electrophiles in electrophilic aromatic substitution reactions. Like Lewis acids, protonic acids also can enhance the electrophilicity of carbonyl carbons. One equivalent of acetone will react with two equivalents of phenol to form the now notorious compound bisphenol A. The net reaction is indicated here. CHO OH H2SO4 OH HO НАС CH CH, bisphenol A phenol acetone (Note that 2 equivalents...

Have you ever considered how we come to understand the world around us? Think about that question for a minute. What is science, and how do we use it to solve real-world problems? In our first discussion, I want to delve into thinking about the nature of biology. This includes what it is, the major themes, and how we come to form claims or knowledge. You should spend approximately 3 hours on this assignment. Instructions Use the text readings and...

VSEPR Objective : This lab is to study the shape and polarity of molecules using VSEPR theory with emphasis on sigma bonds (Part 1) and pi bonds and resonance (Part 2) Procedures: Nothing to do before the lab. We are making the models together in class. Prelab Questions : PART 1: (PL1) Draw the Lewis dot structure of each compound (as having covalent bonds).

TSD.1 In this problem, we will see (in outline) how we can calculate the multiplicity of a monatomic ideal gas This derivation involves concepts presented in chapter 17 Note that the task is to count the number of microstates that are compatible with a given gas macrostate, which we describe by specifying the gas's total energy u (within a tiny range of width dlu), the gas's volume V and the num- ber of molecules N in the gas. We will...
