  1. Sau cov atoms ntawm cov saw ntev tshaj plaws horizontally nyob rau hauv qhov kev txiav txim nyob rau hauv uas lawv txuas nrog.
  2. Sau tag nrho cov ligands ntawm ib lub atom tam sim ntawd mus rau nws txoj cai, nrog subscripts rau ntau.
  3. Muab cov polyatomic ligands nyob rau hauv lub voj voog.
  4. Siv daim ntawv cog lus meej raws li xav tau los qhia meej cov ntawv txuas.

Dhau li ntawm no, dab tsi yog condensed structural formula muab piv txwv?

Nws qhia tag nrho cov atoms, tab sis tshem tawm cov ntawv cog lus ntsug thiab feem ntau lossis tag nrho cov kab rov tav ib daim ntawv cog lus. Nws siv cov kab lus los qhia tias pawg polyatomic nyob rau hauv ib qauv yog txuas rau qhov ze tshaj plaws uas tsis yog-hydrogen atom ntawm sab laug. Yog li cov condensed qauv qauv ntawm propan-2-ol yog CH3CH(OH)CH3.

Ib yam li ntawd, dab tsi yog condensed structural formula rau ethanol? Ethanol's chemical formula yog C2H6O . Cov tshuaj no tuaj yeem sau ua CH3CH2OH lossis C2H5OH . Nws yog tsim los ntawm cuaj atoms uas suav nrog ob lub carbon (C) atoms, rau hydrogen (H) atoms, thiab ib qho oxygen (O) atom.

Yuav ua li cas koj sau ib tug condensed structural formula rau benzene?

Rau tshuaj benzene , cov molecular formula yog C6H6, thiab yog li ntawd muaj rau atoms ntawm carbon thiab rau atoms ntawm hydrogen nyob rau hauv ib molecule. Ceeb toom tias cov molecular formula yog ib txwm ib co ntau ntawm empirical qauv (6 x CH = C6H6).

Qhov txawv ntawm cov qauv qauv thiab cov qauv condensed yog dab tsi?

1 Teb. Ernest Z. A qauv qauv siv cov kab los qhia cov ntawv cog lus nruab nrab cov atom. A condensed qauv qauv oits feem ntau lossis tag nrho cov ntawv cog lus.
