Sry guys mera answer wrong h... Actually tuke pe diya tha and even mene abhi amine padha bhi nhi h

Anurag Yadav 7 years, 9 months ago

In case of alcohols difference in electronegativity of oxygen and hydrogen is greater than between nitrogen and hydrogen in amines. Hence alcohols can form relatively stronger hydrogen bonds with water than amines can do.Thus alcohols are more soluble than amines.

I think amine because it can form more no. of bond while mixed with water..

That's OK. Be thorough with Name reactions, and all the equation given in the organic part. That would be quite practical. Be good at arraging in the required order. Reasoning p, just go through examples and intext questions. Then go for distinction pairs. And then proceed with mind maps for conversion . You may thank me if you do these things religiously well,
