The IUPAC name of given ether has to be chosen from the given options. Concept Introduction: Any organic molecule can be named by using certain rules given by IUPAC (International Union for Pure and applied chemistry). IUPAC name consists of three parts in major namely Prefix suffix and root word. Prefix represents the substituent present in the molecule and its position in the root name. Suffix denotes the presence of functional group if any in the molecule. It can be an alkene , alkyne , alcohol, carboxylic acid , alcohol etc. Root word represents the longest continuous carbon skeleton of the organic molecule. IUPAC rules for naming ether: ✓ The base name is found from the longest carbon chain present in ether. ✓ The suffix –yl has to be changed to –oxy in order to obtain the alkoxy group name. For example, ethyl becomes as ethoxy, methyl becomes as methoxy etc. ✓ Alkoxy name has to be placed first with the number (carbon atom to which the alkoxy group is attached) followed by the base name.

Question

1) Look at the ideal results. Were your predictions accurate, and how did they compare with your results? 2) You used aseptic technique during this lab. Why is it important to work in a sterile manner when working with bacteria in the lab? 3) Why are the cells incubated at 42°C?

Interpretation Introduction

Interpretation:

The IUPAC name of given ether has to be chosen from the given options.

Concept Introduction:

Any organic molecule can be named by using certain rules given by IUPAC (International Union for Pure and applied chemistry). IUPAC name consists of three parts in major namely Prefix suffix and root word.

Prefix represents the substituent present in the molecule and its position in the root name.

Suffix denotes the presence of functional group if any in the molecule. It can be an alkene, alkyne, alcohol, carboxylic acid, alcohol etc.

Root word represents the longest continuous carbon skeleton of the organic molecule.

IUPAC rules for naming ether:

✓ The base name is found from the longest carbon chain present in ether.

✓ The suffix –yl has to be changed to –oxy in order to obtain the alkoxy group name. For example, ethyl becomes as ethoxy, methyl becomes as methoxy etc.

✓ Alkoxy name has to be placed first with the number (carbon atom to which the alkoxy group is attached) followed by the base name.

Overview of Transformation Protocol -Prepare competent bacteria for transformation: Treat starter E. coli bacteria with CaCl2and Competent Cell Solution (CCS). Store on ice until transformation procedure. Competent cells are cells that are likely to take up foreign DNA and be transformed. This step increases the likelihood that the E. coli cells will take up the introduced vector and be transformed. -Transformation procedure: Obtain two microcentrifuge tubes containing your competent cells. Label one tube +DNA and one -DNA. Add CaCl2 to both tubes. Add the transformation mix containing the plasmid DNA to the tube labeled +DNA. Do not add any plasmid DNA to the -DNA tube. Incubate both tubes on ice for 10 minutes. Then, place both tubes in a 42\deg C water bath for 45 seconds. Replace the tubes in an ice bucket for 2 minutes. Add recovery broth to both tubes. Incubate both tubes in a 37 C water bath for 5 minutes. Questions: 1) What differences would you expect to see between the…
