Question
A December 2023 Nature Astronomy paper reported the discovery of this molecule in the plumes of Enceladus. For 10 points each:
[10m] Name this molecule, of interest to astrochemists as a precursor to many molecules of life. On Earth, this molecule reacts with an aldehyde in the presence of ammonia to form amino acids via the Strecker synthesis.
ANSWER: hydrogen cyanide [or HCN; accept prussic acid]
[10h] Hydrogen cyanide may be produced in interstellar clouds via one of these reactions, rare on Earth, in which a polyatomic cation and an electron react, forming two neutral molecules.
ANSWER: dissociative recombination
[10e] The polyatomic cation progenitor to hydrogen cyanide must have this geometry for dissociative recombination to occur. Atoms are sp-hybridized in molecules with this geometry.
ANSWER: linear
