This Gas Decomposes in Light! Liquid Hydrogen Telluride: Synthesis, Reactions, and Hazards.

Hey! This video is about hydrogen telluride and its photodissociation. It was a very long and arduous synthesis, but I managed to obtain several milliliters of liquid H2Te.
Regarding the smell, I wouldn’t say that its smell is similar to garlic, more like that of a just burnt match head. However, I can’t be sure about this; perhaps in high concentrations there is a similarity to the garlic smell.
The main thing is that after this synthesis I don’t smell anything special :D

Now do bismuthane.

[@heorhiypavlovych9779]

that would be exciting to see preparation and reactions of BiH3, accordingly to the literature it is not so easy to make and very unstable.

[@erics3737]

probably would be more interesting to make Stannane, which would be easier to handle than Bismuthane.@@heorhiypavlovych9779

[@BobWidlefish]

Yes!

I actually just got done working with hydrogen telluride and tellurols last week, as well as telluroacetone. Loved your video Felix, as always! Only wish I had tried burning what I made, that blue flame is magical!

[@metal_modifier]

Oh my god, he's finally done it

[@ArpadDinka]

May I ask you to tell us about telluroacetone by details?

[@herrhaber9076]

tellurols ? That's something I'd like to see. From a very very long distance :) Joke apart, I imagine they decompose quite readily ?

[@LabCoatz_Science]

@@herrhaber9076 yeah, they decompose pretty quickly in air (the glassware at one point became coated in a tellurium mirror as the compounds decomposed), so smelling them was a bit challenging, but in the end I did get a few whiffs. Overall, they maintained the typical "leek-like" natural gas smell, but with a unique bleachy or metallic tint. Allyl tellurol was more garlicky, probably because the similar allyl mercaptan and allyl sulfides are actually found in garlic, but again, it had this organic bleach-like smell that was very weird.

[@herrhaber9076]

@@LabCoatz_Science Oh I never imagined they would decompose so fast that smelling them could be challenging. Maybe it is for the best :)

[@oitthegroit1297]

That was so cool! Thank you for taking the time and effort to show us these cool reactions.

[@pauldietz1325]

Hydrogen telluride is thought to be the reason the Earth is depleted in tellurium compared to its abundance in carbonaceous chondrites. The gas escaped as the Earth formed. CdTe is the second most commonly used semiconductor for PV cells (after silicon), so if we had more tellurium we could make more of these. They are more tolerant of high temperature than silicon PV cells, so they have advantages in hot desert regions.

Finally, for years I have always wanted to see the properties of the heavier hydrogen chalcogenides especially hydrogen telluride on video, thanks for this awesome video! I see hydrogen chalcogenides get more unstable as we move down from water to hydrogen telluride.

[@andrews.4780]

Wow I just got done watching Poor Man’s Chemist’s video on testing his copper telluride right before this. This is impressive tellurium chemistry I love these demonstrations you do with exotic elements and compounds!

[@tracybowling1156]

Thank you so much for all of your hard work on this video. It was excellent. Tellerium has a beautiful flame. I never would have seen it if not for you. You're the best, Felicks!

[@hedgeclipper418]

Really cool to see someone demonstrating this on KZbin! I recently had to make hydrogen selenide through a similar process, and I thought that was nerve-wracking. One issue is that buying Al2Se3 or Al2Te3 is quite expensive, as you mentioned. However, it can be synthesized from the elements, but it requires a very high temperature. One must ignite magnesium in a crucible a few times to melt the elements together. And if it's done in an oxygenated environment, apparently it evolves a lot of chalcogen oxide fumes. I would be really curious to see how this goes. If you synthesize some aluminum telluride, I will at least try synthesizing aluminum selenide!

[@nickbz1303]

And now I will be actively looking into getting a tellurium vapor lamp; that emission spectrum is GORGEOUS!

[@nickbz1303]

Did some of my own digging and posting again for safety; seems like there's a healthy bit of UVC in tellurium's emission spectrum, so probably not the best pretty light to stare at. Really sucks to have UV as my favorite color. (That "high energy" blue-gray of an overcast day has always been magical to me)

[@darmok3171]

[@alllove1754]

Always a pleasure watching your channel. You really blew up (went viral level) after 300 viewers! ❤

[@StuffandThings_]

IIRC you can make tellurides, stannides, and bismuthides with other metallic elements as the cation! That might be a fun thing to try sometime, even if the chemistry isn't the most visually impressive. An ionic (or at least partially so) compound between two metallic elements is a really fascinating phenomenon and I doubt there's much out there about these compounds. A few even occur naturally so it shouldn't be too too hard to pull off.

[@TheCaptainLulz]

Such an underutilized and underappreciated element.

Why would Tellurium and aluminum burn like that? 2 metals with no oxidizer… It looked like flash powder almost. I wonder how that would burn with a chlorate mixed in? Or would that be bad to do? I’m not a chemist… Just a firework enthusiast haha

[@erics3737]

I mixed powdered aluminum with small pieces of tellurium in a test tube and it didn't explode. In this case all you need to get hydrogen telluride is water, not acid. Woof, vile odor. Possibly the most dangerous substance I ever made. I didn't know about the photo decomposition. Interesting.

[@GenosseRot]

Tellurium is not a metal but a metaloid. It stands in the 6th main group and is kinda similar to the other elements in that group (Oxygen, sulfur and selenium). In the reaction with zinc or aluminium it acts as the oxidizer just as sulfur for an example would.
