Transesterification occurs when an alcohol (in excess) reacts with an ester. a)

Question

Transesterification occurs when an alcohol (in excess) reacts with an ester.

a) Draw the ester formed when ethyl pentanoate reacts with methanol.
Input the SMILES string generated via the JSME editor.  

b) Input the name of this ester.
Input a name.  Do not use common names.

c) What is the name of the other product (what we will call a by-product.)
Input a name.  

Biodiesel is a biofuel made via a transesterification reaction between an oil or fat molecule and a small alcohol.

d) If methanol is used as the alcohol in excess to react with the oil molecule given in this link (click here) draw the skeletal structure of the biodiesel molecule that can be used as fuel to power modern diesel engine vehicles (draw out the molecule - do not use the X tool).
Input the SMILES string generated via the JSME editor.  

e) How many moles of biodiesel can be obtained from the transesterification of one mole of oil (using excess alcohol)?

1, 2, 3, 4, 5, 6, 7, 8

f) There is a by-product that is formed along with the biofuel. Draw the skeletal structure of the other product.
Input the SMILES string generated via the JSME editor.
