It's a nucleophilic addition reaction because a nucleophile (HCN) is added to a electrophile (benzaldehyde).
This is a addition reaction because two molecule combine to form a single molecule

Can you check my answers please? To answer the questions below use the following information: Cyanohydrins are important intermediates in the synthesis of c-hydroxycarboxylic acids from ketones and aldehydes. The nitrile functional group can be hydrolyzed by aqueous acid to yield a carboxylic acid. Nitriles can also be hydrolyzed to carboxylic acids using aqueous base. Unfortunately, when a cyanohydrin is treated with aqueous base the original carbonyl compound is isolated OH CHCOOH HO CN OBU H HCEN H NAOH H20...
One example of a first order reaction is the isomerization of hydrogen iso-cyanide to hydrogen cyanide: HHC(g) rightarrow HCN(g) If the rate constant at a particular temperature is 4.403 times 10^-4 see^-l, what mass of remains after 1.50 hours if a 1.000 gram sample of HNC was present at the beginning of the reaction?

When an aldehyde or ketone undergo a nucleophilic attack, the reaction follows a nucleophilic addition mechanism. Conversely, carboxylic acids and their derivatives are known to undergo nucleophilic acyl substitution. Even though all of these functional groups are defined by the carbonyl group, they react very differently. In 1-3 sentences, explain why an aldehyde and a carboxylic acid derivative follow different mechanistic pathways in the presence of a nucleophilic species.
Why do aldehydes undergo nucleophilic addition reactions while acyl chlorides undergo nucleophilic acyl substitution reactions? Once the nucleophile adds to the aldehyde, the tetrahedral intermediate is too sterically hindered to eliminate one of the attached groups. Because an Sw2 substitution can best take place on the sphybridized carborwyl carbon of the acyl halide. Once the nucleophile adds to the aldehyde, neither H" nor Rºcan function as a leaving group. so a substitution cannot take place. The carbonyl carbon of the...
9) 9) Why do aldehydes undergo nucleophilic addition reactions, whereas esters undergo nucleophilic acyl substitution reactions? A) The carbonyl carbon of an ester is more electrophilic than that of an aldehyde. B) Once the nucleophile adds to an aldehyde, neither H- nor R-can be eliminated because they are strongly basic. C) Aldehydes are more sterically hindered than esters. D) The ester carbonyl carbon is sp3 hybridized while the aldehyde carbonyl carbon is sp2 hybridized. E) Once the nucleophile adds to...
