1.	Order of base strength of the compoundsCH2 NH2□□(a) IV(c) II > III>IV>I(b) III> Il > IV >,I(d) II> IH> I> IV D>II>I > III
Answer» option B is correct. strong acid forms weaker base and COOH is stronger acid than Ph-OH , so its conjugate base will be Ph-O- > COO- This is due to lone pair on the nitrogen and extra -ve charge. so iii> ii but due to less Electronegativity C with -ve charge is a better donor then may be its an exception.. you can't do much but accepting the fact

Answer»

option B is correct.

strong acid forms weaker base

and COOH is stronger acid than Ph-OH , so its conjugate base will be Ph-O- > COO-

This is due to lone pair on the nitrogen and extra -ve charge.

so iii> ii

but due to less Electronegativity C with -ve charge is a better donor

then may be its an exception.. you can't do much but accepting the fact
