Question
Because titanocene changes color when exposed to oxygen, it can be used to test the integrity of these pieces of equipment. For 10 points each:
[10m] Name these containers that provide an inert environment for sensitive laboratory work. Organometallics are bagged into these devices before a user enters them through a rubber port.
ANSWER: glove boxes
[10e] Oxygen is purged from a glove box using nitrogen or this inexpensive inert gas that makes up about one percent of Earth’s atmosphere.
ANSWER: argon [or Ar]
[10h] This other chemical probe of glove box integrity, which smokes in the presence of oxygen, was the first covalent organometallic compound to be discovered. This pyrophoric four-carbon compound is a popular chain-shuttling agent for making block copolymers.
ANSWER: diethylzinc [or DEZ]
