Benzaldehyde has a benzene ring where formaldehyde has a hydrogen atom. (C6H5CHO as opposed to HCHO). Formaldehyde is used as a biocide and a disinfectant. It is a nasty substance and may be a carcinogen. Benzaldehyde on the other hand is used as a food additive to give an almond flavour.
Benzaldehyde has the formula C7H6O, it has the carbonyl carbon of the aldehyde bound to a benzene ring. You can't have a =O unit bound directly to the benzene ring because you would have a carbon with five bonds.
benzene with 2~chloropropane in presence of aluminiumchloride
The functional group of biphenyl is aromatic ring, benzene.
treat benzene with CO/CuCl/AlCl3/HCl to make a benzaldehyde (i.e. add CHO on benzene ring), then Zn(Hg)/HCl to make toluene
Benzaldehyde is an organic compound with the formula C6H5CHO. It is an aldehyde that has an almond-like odor and used for making perfumes.

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.
first oxidise the benzaldehyde to carboxylic acid(benzoic acid) using any oxidising agent .then add SOCl2
The Gatterman reaction is used to convert benzene to benzaldehyde (and derivatives). You need to use the Sandmeyer reaction to add iodo groups to aromatic rings. I think textbooks sometimes gets the two reactions mixed up.
benzene after oxidation convert into benzoic acid. zahra khan.
Jones reagent (Dichromic acid; H2Cr2O7)
Convert the benzene into Phenol which is a good antiseptic material.
