Constitutional isomers of C2H4O | Aldehyde & Ketone - Dr K - Duration: 1:52.The question is asking us to draw out all possible aldehyde and ketones
isomers for C2H4O. Aldehyde has a carbonyl functional group which is
C=O connected to a hydrogen. Note that the carbonyl group in aldehyde
is always at the first carbon, whereas for ketone, it also has a
carbonyl group but it is sandwiched between two carbons, so, the difference
between aldehyde and ketone is that they both have carbonyl group but in aldehyde
there's a H connected next to it. In ketone, both sides are carbon. So, let's
start with aldehyde. Since we only have two carbons, let's place them next
to each other and then we'll add in the carbonyl group and hydrogen right next
to the carbonyl carbon. Then we'll fill in the remaining bonds on carbon with hydrogens.
Since carbon makes four bonds, the carbon on the right will connect to
three hydrogens like this. So, it looks like we've completed our first isomer.
There is no other way we can draw aldehyde with two carbons, so, let's see
if we can draw any isomer for ketone. As mentioned earlier, the functional group
for ketone is carbonyl carbon and sandwiched between two carbons like this.
However, the formula that is given, C2H4O, only has two carbons and in order to
draw a ketone we need at least three carbons, so, that means there's no ketone
for C2H4O. So, there is only one structure for aldehyde and none for
ketone for C2H4O. If you're interested in drawing other isomer
aside from aldehyde and ketone for this formula, let me know in the comments and
I'll post a video for it.
I hope you find the video helpful. Do subscribe and thanks for watching!

V (BTS)- Stigma || Learn Korean with K-Pop - Duration: 8:34.Hello, everyone! My name is Natalia and I'm your Korean language study buddie~!

Nope, it's not! It's not~
It's just that on V's birthday, I'll be preparing to board a plane. So~ I'm filming this video early!
But, I'm going to pretend it's V's birthday!
Today we will be learning vocabulary with V's song, "Stigma!"
But before that, we must give V a birthday message, right? Right!
V, or Taehyung..
Happy Birthday!
My clapping is super awkward, right? It's really...
weird.. Even though I know it's weird, I'm going to continue doing it.
