Question

1. What Solvent would you choose to carry out the following reaction?

CH3CH2O-H + Na+  -:H -------> CH3CH2O-  Na+ + H2

2. Starting with 3-methylbutyne and ethyl bromide, show how you could synthesize 2-methyhexane?

(CH3)2CHC?C-H + Br-CH2CH3 -----> (CH3)2CHCH2H2CH2CH3

**Show me how...

3. Show the flow of electrons and complete the acid base reaction:

Show the flow of electrons and complete the acid base reaction:

Explanation / Answer

1. The solvent used here is water + DMSO. DMSO is the solvent which decreases the acidity of the water.

2. (CH3)2CHC?C-H + Br-CH2CH3 -----> (CH3)2CHC?C-CH2CH3 + H2/Pd ----------------->(CH3)2CHCH2CH2CH2CH3

3. The flow of electrons which is indicated in the question is correct

CH3NH3+ + OH- ---------------> CH3NH2 + H2O

CH3COO- + H3O+ ---------------> CH3COOH + H2O
