H3N+ (2)
N+H3. (3)
COOH
(1)
WRITE ORDER OF ACIDITY FOR 1,2&3
a) 3>1>2 b) 1>2>3
c) 1>3>2 d) 2>1>3
39I'm not being able to explain this on basis of conjugate bases...so I'll just be direct.
The -I effect of -COOH increases the acidity of -NH3+ and the same for -NH3+ on -COOH.
Now the inductive effect of (1) on (2) is stronger than that of (2) on (1). Hence (2) is more acidic than (1). (3) is obviously the weakest acid.
So the acidity order is 2 > 1 > 3.
23i go with 1 > 2 > 3
carboxylic acids are more acidic than -NH3+ ( as R-NH2 are more basic than RCOO-)
so 1 will be most acidic
now due to -I of COOH grp , 2 is more acidic than 3
so 1 > 2 > 3
wats the ans given ?
1i will go with 1>2>3 becoz obviously due to -i effect 2>3 but -i effect is a weak effect and so much change in acidity of cooH should not take place.
