  • Thank you good sir (british accent)

  • i like the colors <3

  • Thanks.

  • @Ir0xorz You're saying that the two CH2's would be facing the top CH2------CH2 and the one towards the bottom, right? but that is probably just a different confirmation, like I'm sure you can change the shape to allow the molecule to be achiral. all the substituent are the same after-all.

  • @Ir0xorz the hydrogen would be coming out of the screen if you rated it 180 degrees

  • do you get paid?? You helped a bunch.

  • Why would anyone dislike this? Assholes

  • I am taking o. Chem. In college and this really helped thank you so much

  • omg thank you!!! this vid helped me a lot!!!

  • @lakers1120 No, A molecule can contain chiral carbons and still be achiral. A chiral molecule is a molecule that contains a stereocenter (chiral carbon) and who's mirror image is Not superimposable. If there is a molecule that say, contains two chiral carbons, and has a plane of symmetry, then it's mirror image would be superimposable, so even though the molecule contains chiral carbons it wouldn't be a chiral molecule do to the fact that it's mirror image is superimposable

  • @lnr08f

    dude. perfect explanation, just what I needed. thanx

  • thanks for your sharing

  • About the last example, can't you rotate the molecule by 180 degrees horizontally ("x-axis") and then 180 degrees again by the "z-axis" to get it into a superimposable form to its mirror image?

    (sorry for the bad use of terminologies)

  • @CenTiSoN ya i think he made a mistake. its achiral molecule with one carbon stereocenter

  • mama methaan

    en ethaan

    papa enz

    perfecte

  • homochirality proves evolution can never happen,evolutionists would rather believe in some chemistry unknown to science

  • @5tonyvvvv Are you fucking stupid? Please explain to me how this disproves evolution? You do know that evolution is supported by BILLIONS of pieces of evidence and FACTS. Evolution is a FACT.

    Now please, explain how this disproves evolution?

    I really want to debunk your sorry ass.

  • @MW2Addiction PRove youself

  • [M]ethyl - [E]thyl - [P]ropyl - [B]utyl

    Me Eat Peanut Butter!

    Best way to memorize these 4 :P

  • @Justin2k7 hahaha! :)

  • @ 1:23 . isnt the Cl attached to H?

    C-H-Cl or Cl-C-H ?

    And in anycase , wont the answer be same?

  • @Divjot04 no.

  • Bromo......Chloro.....Fluoro..­..methane!

    lol

    Awesome video. Extremely helpful!

  • I loooooooooove you. I owe you like...my life LOL

  • so if you dont have a chiral center...(with 4 different atoms or groups attached to it) then its not chiral?

  • thanks mate, you just saved my life! :D

  • should confirmation not be conformation?

  • :D TYTY
