The product of reacting benzoyl chloride with ammonia is?

Acid chlorides react with ammonia to form amides through nucleophilic acyl substitution. The lone pair on ammonia attacks the carbonyl carbon of benzoyl chloride, a tetrahedral intermediate forms, and chloride leaves. After deprotonation, benzamide is produced (with ammonium chloride as a byproduct). This path is favored because acid chlorides are highly reactive toward nucleophiles and readily convert to amides in the presence of ammonia. Benzaldehyde would require oxidation or a different transformation, benzoic acid would result from hydrolysis of the acid chloride, and aniline would come from a reduction or different route, not from straightforward reaction with ammonia.
