Phenol isa very weak acidand the position of equilibrium lies well to the left. Phenol can lose a hydrogen ion because the phenoxide ion formed is stabilised to some extent. The negative charge on the oxygen atom is delocalised around the ring. ... That is why phenol is only a very weak...
Which of the following bonds or forces is the weakest one? a) bond between C and Cl in CCl_4 b) bond between two carbon atoms in C_2H_6 c) hydrogen bond between HF molecules d) bond between K and Cl in KCl Which ...
HF < HCl < HBr < HI is the correct increasing order of the acidic strength. Key Points The acidic strength is the tendency of acid to be able to dissociate into a proton, H+, and an anion. A strong acid completely ionizes in a solution and a weak acid only partially ion...
