Write the reaction equation C3H8-C3H7Br-C3H7OH-C3H7COH-C3H7COOH- (HCOO) 2Ca

Let’s write the equations:
C3H8 + Br2 = C3H7Br + HBr – substitution reaction, bromopropane was formed;
С3Н7Br + KOH = C3H7 – OH + KBr – exchange, propanol was obtained;
С3Н7 – ОН + CuO = C3H7COH + Cu + H2O – qualitative reaction for alcohol, propanal and copper were formed;
С3Н7СОН + 2Cu (OH) 2 = C3H7 – COOH + Cu2O + H2O – oxidation of propanal with copper oxide, propionic acid is released;
C3H7 – COOH + CH3 – OH = C3H7 – COO – CH3 + H2O – esterification, propionomethyl ether was obtained;
C3H7 – COO – CH3 + H2O = C3H7 – COOH + CH3 – OH – ether hydrolysis, methanol was formed;
CH3 – OH + CuO = HCOH + Cu + H2O – oxidation of methanol, methanal was obtained;
НСОН + Ag2O = HCOOH + 2Ag – qualitative reaction to aldehyde, methanoic acid was formed;
2НСООН + Ca = (HCOO) 2Ca + H2 – substitutions, calcium formate was obtained.
These reactions show the connection between alkanes and oxygen-containing organic substances.
