Let’s implement the solution:
1. Let’s make a chain:
C3H8 – C3H7Cl – C3H7OH – C3H6O – CH3 – CH2 – COOH – CH3 – CH – Cl – COOH – CH3CH (NH2) – COOH;
2. Let’s write down the equations:
C3H8 + Cl2 = C3H7Cl + HCl – substitution reaction, chloropropane was obtained from propane;
С3Н7Cl + KOH = C3H7 – OH + KCl – exchange, propanol was formed;
С3Н7 – ОН + CuO = C3H6O + Cu + H2O – propanol oxidation, propanal is released;
C3H6O + Ag2O = C3H6O2 + 2Ag – oxidation of propanal, obtained propanoic acid;
CH3 – CH2 – COOH + Cl2 = CH3 – CHCl – COOH + HCl – substitution, chloropropanoic acid was released;
CH3 – CHCl – COOH + NH3 = CH3 – CH (NH2) – COOH + HCl – exchange, 2-aminopropanoic acid was obtained.
These reactions confirm the link between alkanes and amino acids.
