Mavzu: Bir va ikki asosli kislotalarning kuchini aniqlash. Kislatalikka ko’rsatadigan induksion va solvatik tasirni aniqlash

Masalan: chumoli kislata HCOOH sirka kislatadan CH3COOH kuchli kislata xossaga ega, chunki atsetat ionining (CH3COO-) asosliligi formiat ioni (HCOO-) asosliligidan yuqori

Masalan: chumoli kislata HCOOH sirka kislatadan CH3COOH kuchli kislata xossaga ega, chunki atsetat ionining (CH3COO-) asosliligi formiat ioni (HCOO-) asosliligidan yuqori

HCOOH > CH3COOH

kislatalik

* Sirka va xlorsirka kislatalar solishtirilganda xlorsirka kislata sirka kislataga nisbatan taxminan 100 barobar kuchli ekanligi aniqlangan

CH3COOH < ClCH2COOH

100 barobar kislatalik kuchi

Bunga sabab xlor atomining kuchi elektronaakseptorlik xossasiga ega ekanidir

• Bunga sabab xlor atomining kuchi elektronaakseptorlik xossasiga ega ekanidir
• CH3COOH H+ + CH3COOH-
• ClCH2COOH H+ + ClCH2COOH-
• Ya`ni quyidagicha (4:1)

Biz yana xlorsirka kislota

dixlorsirka kislota

trixlor sirka kislatalarni solishtirsak shu ketma ketlikda kislotalik kuchi ortadi. (4:2)
