1.	Which of the following is the least acidic?A. `H_2O`B. `CH_3CH_2OH`C. `CH-=CH`D. `NH_3`
Answer» Correct Answer - D Order of relative acidity `H-OHgtH-ORgtH-C-=CHgtH-NH_2` order of relative basicity `overline(O)Hltoverline(O)Rltoverline(C)-=CHltoverline(N)H_2` Note that though N is more electronegative than C atom the basic character of `overline(N)H_3` predominates over its acidic character.
