Alright — let's do this. The question asks for an organic compound that does not react with both hydrogen cyanide (HCN) and hydroxylamine (NH_2OH). 1. Reaction with Hydrogen Cyanide (HCN): Hydrogen cyanide undergoes nucleophilic addition reactions with compounds containing a carbonyl group (C=O), specifically aldehydes and ketones, to form cyanohydrins. Alkanones* (ketones) have a C=O group and react with HCN. Alkanals* (aldehydes) have a C=O group and react with HCN. Alkanoic acids* have a C=O group as part of a carboxyl group (COOH), but their carbonyl carbon is less reactive towards nucleophilic addition compared to aldehydes and ketones, so they generally do not form cyanohydrins. Alkenes* have a carbon-carbon double bond (C=C) but no C=O group, so they do not react with HCN in this manner. 2. Reaction with Hydroxylamine (NH_2OH): Hydroxylamine reacts with compounds containing a carbonyl group (C=O), specifically aldehydes and ketones, to form oximes. This is a nucleophilic addition-elimination reaction. Alkanones* (ketones) have a C=O group and react with NH_2OH. Alkanals* (aldehydes) have a C=O group and react with NH_2OH. Alkanoic acids* do not typically react with hydroxylamine to form oximes at the carboxyl carbon. Alkenes* have no C=O group, so they do not react with NH_2OH to form oximes. Based on this analysis: Alkanones and Alkanals react with both HCN and NH_2OH. Alkanoic acids generally do not undergo these specific reactions. Alkenes do not have a carbonyl group (C=O) and therefore do not undergo these characteristic reactions with either HCN or NH_2OH. Thus, an alkene is the compound that does not undergo a reaction with both hydrogen cyanide and hydroxylamine. The correct option is B.
