H20 is stonger than NH3 and H2S becauze oxygen is more electronegative 0H. HO is stronger than NH3 neanygen is less electroregtive and H2S is stronger than H2O because S is smaler than o. QUESTION 28 For esch of the folwoing resctions, identity the Lewis Acid and the Lowis Base S03 A Lewis Acid 40 B Lowis Base QUESTION 29 For each of the folowing reactions, idertly the Lewis Adid and the Lowis Base 2n2 A Lowis Acid B Lewis Base QUESTION 3 A Lewis Base me anything

Explanation / Answer

According to Lewis theory of acid-base reactions, bases donate pairs of electrons and acids accept pairs of electrons.

(28) SO3 + HO- ----> HSO4-

SO3 is the lewis acid since it accepting an electron pair to form a coordinate covalent bond
OH- is the lewis base, since it has the electron pair to be donated .

(29) 4NH3 + Zn2+ ---> Zn(NH3)42+

Here Zn2+ is the Lewis acid & NH3 is the Lewis base.

(30) SiF4 + 2F- ----> SiF62-

SiF4 is a Lewis acid

F- is a Lewis base
