example of how aromaticity affect drug function

Bacteria that have a composition of C5H7O2N. Determine the BOD for 30mg/L, following the following formula:

C5H7O2N + O2 -> CO2 + H2O + NH3

NH3 + O2 -> NO3 + H+ + H2O

air with concentration of 9 moles/m³ oxygen and 16 moles/m³ of nitrogen at stp. determine the partial pressure of oxygen and nitrogen in 1.0 m³ in air. 

1. Draw a formula of 3’-uridylic acid, designate types of bonds between the fragments in the molecule. Write schemes of acidic and alkaline hydrolysis of this nucleotide.

2 Draw a structural formula of messenger RNA fragment that was rewritten from the fragment TCA of DNA.

3 Write schemes of hydrogenation reaction of dioleostearin and its acidic and alkaline hydrolysis. How is it possible to confirm the unsaturation of dioleostearin? Write schemes of two reactions, designate their visual results. 

Chemical reaction between dimethylformamaide (DMF) and acrylic?

The reaction of 2,3-dimethylbuta-1,3-diene and HBr (1:1 mole) gives two products I and II

i) which of the two products (I or II) is the 1,4-addition product? Explain the significance of the number 1 and 4?

ii) which of the two products would be more stable? Explain.

iii) what is the structure of the carbonation that leads to I and II.

iv) which product I or II is the kinetic product? Explain your choice.

v) which product I or II is the thermodynamic product? Explain your choice.

The reaction scheme shows the synthesis of 2-methylpentnoic acid from diethyl malonate (malonic ester).

i) The reagents in step 1 are:(i) EtO and (ii) an alkyl halide. What alkyl halide is required in step 1? Draw a mechanism for the reactions that occur in step 1.

ii) Suggest reagents for step 2.

iii) suggest reagents for step 3. Name this type of reaction.

iv) Step 4 is a thermal decarboxylation reaction. Show a mechanism for the decarboxylation in step 4 that results in the formation of 2-methylpentnoic acid, and explain why the decarboxylation of the dicarboxylic acid in step 4 is particularly facile that is it readily occurs.
