Identify products of given reaction:

Which of the following is not a chemical property or identification test for aldehydes? 

$\stackrel{\mathrm{NaOEt}}{\to }\stackrel{1 \mathrm{dil}.\mathrm{NaOH}/\mathrm{\Delta }}{\to }\stackrel{\mathrm{\Delta }}{\to }$ Final product is 

$\mathrm{PhCHO}+{\mathrm{BrCH}}_2{\mathrm{CO}}_2\mathrm{Et}\underset{\left(2\right){\mathrm{H}}_2\mathrm{O}}{\overset{\left(1\right)\mathrm{Zn}}{\to }}\left(\mathrm{A}\right)\underset{(–{\mathrm{H}}_2\mathrm{O})}{\to }\left(\mathrm{B}\right)$

Product $\left(\mathrm{B}\right)$ of the above reaction is:

$?\underset{\mathrm{EtOH},{\mathrm{H}}_2\mathrm{O}}{\overset{\mathrm{\Delta },{\mathrm{CN}}^{-}}{\to }}\mathrm{Benzoin}.$ The reactant is obtained by dry distillation of the calcium salts of which of the following pairs.
