Cia peb saib. Methyl pawg , uas yog ib feem ntawm alkyl functional pab pawg , muaj cov pa roj carbon atom ncig los ntawm peb hydrogen atoms, qhia tias yog CH3. Ntawm lawv cov khoom tshwj xeeb yog muaj peev xwm tsim cov tsis- polar covalent bonds thiab hydrophobicity. Methyl pawg tuaj yeem pom nyob ib leeg lossis ib feem ntawm cov qauv organic.

Ntawm no, puas yog methyl functional pawg polar lossis nonpolar?

Cov methyl pawg yog tus xwb non-polar functional pawg nyob rau hauv peb cov chav kawm saum toj no. Cov methyl pawg muaj cov pa roj carbon atom khi rau 3 hydrogen atoms. Hauv chav kawm no peb yuav kho cov C-H daim ntawv cog lus kom zoo tsis muaj polar covalent bonds.

Tsis tas li ntawd, puas yog txhua pawg ua haujlwm polar? Cov pab pawg ua haujlwm muaj peev xwm qee zaum raug cais raws li muaj polar los yog nonpolar zog nyob ntawm lawv cov atomic muaj pes tsawg leeg thiab lub koom haum. Ntawm cov polar functional pawg yog carboxyl pab pawg pom nyob rau hauv cov amino acids, qee cov amino acid sab chains, thiab fatty acids uas tsim triglycerides thiab phospholipids.

Tom qab ntawd, ib tus tuaj yeem nug, puas yog methyl pawg hydrophobic?

Muaj nuj nqi pab pawg tuaj yeem muab faib ua hydrophobic los yog hydrophilic Raws li lawv cov nqi thiab polarity yam ntxwv. Lub xwb pawg hydrophobic hauv qab no yog cov methyl (CH 3?start subscript, 3, kawg subscript) pab pawg , uas yog nonpolar.

Dab tsi ua haujlwm pab pawg yog polar tshaj?

Carboxylic Acids yog pawg polar feem ntau ua haujlwm vim tias lawv tuaj yeem hydrogen daim ntawv cog lus ntau, lawv muaj lub sijhawm dipole thiab 2 electronegative atoms.
