Only those aldehydes may undergo the aldol condensation which have the alpha hydrogen (hydrogen at carbon adjacent to carbonyl carbon) in benzaldehyde alpha carbon is not present so it can not undergoes the aldol condensation.
Compounds which have CH3CO- group or compounds that can be converted to CH3CO- group undergo aldol condensation. 1-propanol doesn't undergo aldol condensation. However 2-propanol undergoes aldol condensation.
Yes it does, as it has CH3CO- group.
Aldol condensation is the reaction of two aldehydes in the presence of a basic catalyst. The aldol condensation leads to an aldol product, in which an hydroxyl group is attached to the beta carbon of an aldehyde. Claisen condensation is similar to aldol condensation, but is involves two esters instead of two aldehydes. The product of a Claisen condensation is a beta-keto-ester, a compound characterized by an ester with its alpha carbon being a ketone.
All condensation reactions proceed with formation of water (H2O). If you look at the reaction mechanism for Aldol condensation, you will observe that water is formed as an end-product of the reaction.
no, the hydroxyl group must be beta not alpha to the carbonyl group

ethyl acetate undergoes aldol condensation with benzaldehyde. in the aldol product the aceto group undergoes enolisation. Urea attacks through 1,4 addition.

The Claisen-Schmidt reaction involves the condensation of two carbonyl compounds, typically an aldehyde and a ketone, to form an α,β-unsaturated carbonyl compound. In contrast, aldol condensation involves the condensation of an aldehyde or ketone with itself to form a β-hydroxy carbonyl compound. The key difference is the presence of two different carbonyl compounds in the Claisen-Schmidt reaction, while aldol condensation involves one carbonyl compound reacting with itself.
Not really because aldol condensation of 2 CH3CHO would be a major competing process.

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.
no, the hydroxyl group must be beta not alpha to the carbonyl group
well based on my studies two compounds are produced, viz: ethanedial and methanal
