The given chemical reactions show the conversion of acetylene (C2H2) to sodium acetate (CH3COONa) through several intermediate steps. Here is the step-by-step breakdown of the reactions:

C2H2 (Acetylene) -> CH3COH (Acetaldehyde)CH3COH (Acetaldehyde) -> C2H5OH (Ethanol)C2H5OH (Ethanol) -> C2H5Br (1-Bromopropane)C2H5Br (1-Bromopropane) -> C2H4 (Ethylene)C2H4 (Ethylene) -> C2H5OH (Ethanol)C2H5OH (Ethanol) -> CH3COH (Acetaldehyde)CH3COH (Acetaldehyde) -> CH3COOH (Acetic Acid)CH3COOH (Acetic Acid) + NaOH -> CH3COONa (Sodium Acetate)

Therefore, the complete reaction pathway from acetylene to sodium acetate involves a series of chemical transformations.
