Any electron deficient centre will be able to act as a Lewis acid (eg
The dissociation constant Ka for any weak acid in water is:
Large Ka = strong acid (highly dissociated)
pKa = -ive log Ka small pKa = strong acid
Strong acid = weak conjugate base
Strong base = weak conjugate acid and vice versa PART II – REACTIONS OF ALKANES, ALKENSE AND
