Which of these statements is false regarding the following reaction?

Answer & explanation
Correct answer: option 1
The reaction is a reduction from a carboxylic acid to an alcohol. The carboxylic acid has a conjugate base that is stabilized by resonance . Therefore, carboxylic acids readily donate their H+ and thus have a lower pKa than alcohols.
The bond length in a single bond is longer than the bond length in a double bond. The carbon-oxygen bond in the alcohol is therefore longer than the carbon-oxygen bond of the carbonyl in the carboxylic acid reactant.
SOCl2 can convert alcohols to alkyl chlorides through a nucleophilic chloride atom. However, a reaction between an alcohol and an acid chloride does not produce a carboxylic acid, instead it produces an ester.
