A) \[{{H}_{2}}O,{{C}_{2}}{{H}_{2}},{{H}_{2}}C{{O}_{3}}\], phenol
B) \[{{C}_{2}}{{H}_{2}},{{H}_{2}}O,{{H}_{2}}C{{O}_{3}}\], phenol
C) phenol, \[{{C}_{2}}{{H}_{2}},{{H}_{2}}C{{O}_{3}},{{H}_{2}}O\]
D) \[{{C}_{2}}{{H}_{2}},{{H}_{2}}O\], phenol, \[,{{H}_{2}}C{{O}_{3}}\]
Correct Answer: D
Solution :
[d] Such questions can be solved by considering the relative basic character of their conjugated bases which for \[{{H}_{2}}O,{{C}_{2}}{{H}_{2}},{{H}_{2}}C{{O}_{3}}\] and \[{{C}_{6}}{{H}_{5}}OH\] are \[^{-}OH,HC\equiv {{C}^{-}}:,HCO_{3}^{-},{{C}_{6}}{{H}_{5}}{{O}^{-}}\] More the possibility for the dispersal of the negative charge, weaker will be the base. Thus the relative basic character of the four bases isYou need to login to perform this action.
