Benzaldehyde and hydroxylamine will produce oxime ethers. Oxime is any of a class of organic compounds, of general formula RR'C=NOH, derived from the condensation of an aldehyde (R' = H) or ketone with hydroxylamine.
It is the formation of pure benzyl easters in a better and shorter way,
R-COCl + C6H5-CH2-OH = R-CO-O-CH2- C6H5 + HCl
you will get an elimination of water to give a double bonded nitrogen from the amine

Benzylidenecyclopentanone Draw its structure by attaching C6H5-CH= to carbon 2 of cyclopentanone.
The resonating effect of benzene ring makes the removal of hydride slightly difficult as compare to formaldehyde but benzaldehyde also donates hydride as in Cannizzaro;s reaction.
The Perkin reaction by rctn with an ethanoic anhydride and an ethanoate salt.orFirst step: Add CH2(CO2Et)2 along with Na+-OEt and ethanol to benzaldehyde. (carbonyl condensation)Second step: Add H3O+.The Perkin reaction is an organic reaction developed by William Henry Perkin that can be used to make cinnamic acids i.e. α-β-unsaturated aromatic acid by the aldol condensation of aromatic aldehydes and acid anhydrides in the presence of an alkali salt of the acid several reviews have been written. The reaction of phenylacetic acid and benzaldehyde with triethylamine and acetic anhydride to alpha-phenylcinnamic acid is an example of this reaction type.
4nh3 + 5o2 --> 4no + 6h2o
After completion of reaction the residue was treated with saturated solution of Sodium metabisulphite to remove unreacted benzaldehyde
The major product of the autooxidation of benzaldehyde is a crystalline white precipitate of benzoic acid. When few drops of benzaldehyde is exposed to the atmosphere by using a watchglass, it is oxidized to form carboxylic acid salt.

The Schiff reagent is a product of Fuchsine or Pararosaniline. The Schiff reagent is used to test for aldehydes. Benzaldehyde is added to the decolorized Schiff reagent and a purple/magenta color appears.
Benzylidenecyclopentanone Draw its structure by attaching C6H5-CH= to carbon 2 of cyclopentanone.
To get a very accurate volume of hydroxylamine.
Benzaldehyde is the simplest aromatic aldehyde. The oxidizing agent used in Fehling's solution is not strong enough to oxidize the aromatic ring. Therefore Benzaldehyde doesn't show Fehling's test. I hope it helped :)
The resonating effect of benzene ring makes the removal of hydride slightly difficult as compare to formaldehyde but benzaldehyde also donates hydride as in Cannizzaro;s reaction.
Benzaldehyde's liquid density is 1.0415 g/mL. This means 5 mL of benzaldehyde is equivalent to 5.2075 g of liquid benzaldehyde.
The density of benzaldehyde is 1,044 g/cm3.
Reaction of 1-propane-magnesia-bromide with benzaldehyde and destruction of the product with water yields to 1-phenyl-1-propanol.1) 1) Organikum, 21. Aufl., Wiley-VCH Verlag GmbH Weinheim 2001, S. 562
hydroxylamine is a reagent that helps reduce iron
