Sagot :
When ethanol and pbr3 combine, bromoethane and phosphoric acid are created.
PBr3+3C2H5OH------>3C2H5Br+H3PO3
The chemical name for phosphorous tribromide is PBr3. It can be created by the interaction of red phosphorous with bromine and is a Lewis acid or electron deficient chemical that lacks a complete octet. This process is quite exothermic.
It is a colorless liquid mostly utilized for changing various alcohols into their corresponding alkyl bromides. The reaction is an inverted configuration bimolecular nucleophilic substitution reaction. Alkyl bromide is the main byproduct of this process.
Alcohol attacking phosphorous tribromide triggers this reaction's mechanism, which results in the substitution of an alcohol group for a bromine atom.

CH3MgBr = (Grignard reagent compound )
We can add a single carbon atom to make a primary alcohol by reacting a Grignard reagent with formaldehyde.

CH3CH2MgBr+ H2C=O -------> CH3CH2CH2O ----->CH3CH2OH
AQUEOUS ACID: (taking HCL as not mentioned)
CH 3 CH 2 (OH) + HCl ------> CH 3 CH 2(Cl) + H 2 O
Reaction type: double replacement
resulting product: CH 3 CH 2 Cl
