Bond Strength and Acids Lub zog ntawm cov kua qaub feem ntau nyob ntawm qhov loj ntawm 'A' atom: qhov me dua 'A' atom, qhov muaj zog H-A daim ntawv cog lus. Thaum nkag mus rau hauv kab hauv Lub Sijhawm Teem Sijhawm (saib daim duab hauv qab), cov atoms tau loj dua yog li lub zog ntawm daim ntawv cog lus tsis muaj zog, uas txhais tau hais tias cov kua qaub muaj zog dua.
Koj ua li cas txiav txim siab qhov kev txiav txim ntawm cov kua qaub zog?
Yog li ntawd, qhov tseeb ntawm acidity yog D > C > B > A. Li no, qhov kev xaiv raug yog (B).
Dab tsi yog cov kua qaub uas muaj zog tshaj plaws nyob rau hauv kev txiav txim?
Cov kua qaub muaj zog yog hydrochloric acid, nitric acid, sulfuric acid, hydrobromic acid, hydroiodic acid, perchloric acid, thiab chloric acid.
Koj ua li cas cov tebchaw kom nce acidity?
Kev txiav txim ntawm acidity, mus ntawm sab laug mus rau sab xis (nrog 1 yog acidic tshaj), yog 2-1-4-3. Qhov tsawg tshaj plaws acidic compound (thib ob ntawm sab xis) tsis muaj phenol pawg - aldehydes tsis acidic.
Yuav ua li cas nce lub zog ntawm cov kua qaub?
Qhov nce hauv acid zog nrog nce tus naj npawb ntawm cov pa oxygen atomsyog vim ob qho tib si cov nyhuv inductive thiab nce stabilization ntawm conjugate puag. … Qhov txo qis hauv electron ceev hauv O–H daim ntawv cog lus ua rau nws tsis muaj zog, ua rau nws yooj yim dua kom plam hydrogen li H + ions, yog li ua kom lub zog ntawm cov kua qaub.
