Lub ene suffix (qhov xaus) qhia ib alkene los yog cycloalkene. Cov saw ntev tshaj plaws xaiv rau hauv paus npe yuav tsum suav nrog ob qho tib si carbon atom ntawm ob daim ntawv cog lus. Lub hauv paus saw yuav tsum tau suav los ntawm qhov kawg ze tshaj ntawm ob daim ntawv cog lus carbon atom.

Ua raws li qhov no hauv kev txiav txim siab, ua li cas koj lub npe alkenes?

Lub npe Alkenes thiab Alkynes

  1. Alkenes thiab alkynes muaj npe los ntawm kev txheeb xyuas cov saw ntev tshaj plaws uas muaj ob lossis peb daim ntawv cog lus.
  2. Cov saw hlau raug suav ua kom txo qis tus lej muab rau ob lossis peb daim ntawv cog lus.
  3. Lub ntsiab lus ntawm lub compound yog "-ene" rau ib qho alkene lossis "-yne" rau ib qho alkyne.

Ib tug kuj yuav nug, ua li cas koj lub npe hloov pauv alkene? Cov Cai Tseem Ceeb

  1. Nrhiav qhov ntev Carbon Chain uas muaj cov Carbon Carbon ob daim ntawv cog lus.
  2. Muab tus lej qis tshaj plaws rau Carbon Carbon ob daim ntawv cog lus.
  3. Ntxiv cov hloov pauv thiab lawv txoj haujlwm rau alkene ua ntej.
  4. Tom ntej no yog txheeb xyuas cov stereoisomers.

Tsis tas li ntawd, ua li cas koj lub npe cycloalkenes thiab alkenes?

Cycloalkenes muaj npe zoo ib yam. Number tus cycloalkene yog li ob daim ntawv cog lus carbons tau txais tus lej 1 thiab 2, thiab thawj qhov hloov pauv yog tus lej qis tshaj plaws. b. Yog tias muaj kev hloov pauv ntawm ib qho ntawm ob daim ntawv cog lus carbons, nws tau txais tus lej 1.

  1. Suav tag nrho cov carbons nyob rau hauv tag nrho cov molecule. Qhov no yog niam txiv lub npe (eg.
  2. Suav tus naj npawb ntawm cov pa roj carbon monoxide ntawm tus choj taub hau, tom qab ntawd muab tso rau hauv cov hlua khi hauv nqes mus. (eg.
  3. Muab lo lus bicyclo rau ntawm qhov pib ntawm lub npe.
