Why cl is strong reducing agent I.

Abc Efg 8 years, 2 months ago

The standard electrode potential for chlorine is much higher than that of iodine. So, chlorine is indeed a stronger oxidising agent than iodine. The reason for this is that chlorine's valence shell is closer to the positively charged nucleus than that of iodine. So, an electron will be attracted by chlorine more than iodine, making it a stronger oxidizing agent.

Kajal Bhardwaj 8 years, 2 months ago

Because it's electrode potential is more positive

Vineit Kumar Gupta 8 years, 2 months ago

Chlorine has more tendency to gain electron then iodine hence chlorine get oxidised more easily hence its a better reducing agent

Divya Sen 8 years, 2 months ago

The conjugate base of carboxylic acid i.e. carboxylate ion is stabilized by two equivalent resonance structures in which the -ve charge is effectively delocalised between two or more electro-ve oxygen atoms.On the other hand in case of phenols, -ve charge is less effectively delocalised over one oxygen atom and less electro-ve carbon atoms in phenoxide ion.Therefore the carboxylate ion exhibits higher stability in comparison to phenoxide ion.Hence, the carboxylic acids are more acidic than phenols.
