Provide the reagents necessary to convert (S)-3-methyl-3-phenylpentanoic acid to (5)-3-methyl-3-phenylpentanamine.
8090 [49]

Answer:

1. SOCl2/pyridine

2. NH3

3. LiAlH4

4. H2O

Explanation:

In the conversion of  (S)-3-methyl-3-phenylpentanoic acid to (5)-3-methyl-3-phenylpentanamine, SOCl2/pyridine is first added to the  (S)-3-methyl-3-phenylpentanoic acid

This is then followed by the addition of NH3 is subsequently added followed by reduction using LiAlH4 which reduces the carbonyl carbon to an alkane. addition of water completes the mechanism and leads to the formation of the product.

7]how many milliliters of a 1.25 molar hydrochloric acid (hcl) solution would be needed to react completely with 60.0 grams of c
bija089 [108]
According to the chemical equation, the ratio between Ca and HCl for a complete reaction is 1:2.  The moles of Ca can be calculated by mass/molar mass, thus 60.0 g/40 g/mole = 1.5 mole.  So the moles of HCl in the solution is 1.5mole*2 = 3 mole. 

So the volume of HCl solution = Moles of HCl/ concentration of HCl = 3 mole/ 1.25 M = 2.4 L = 2400 mL
