A) RCOOH > HOH > HC \[\equiv \] CH > ROH
B) RCOOH >HC \[\equiv \] CH > HOH > ROH
C) RCOOH > ROH > HOH > HC \[\equiv \] CH
D) RCOOH > HOH > ROH > HC \[\equiv \] CH
Correct Answer: D
Solution :
Carboxylic acid is stronger than alcohol and water because after removal of proton, carboxylate ion is stabilized by resonanace. Hence, correct order of acid strength is \[RCOOH>KOH>ROH>HC\equiv CH\] which is based upon rate of donation of proton of strength of base, order of basic strength. \[\bar{C}\equiv CH>R-\bar{O}>O{{H}^{-}}>RCO{{O}^{-}}\]
