A) (2) > (1) > (3)
B) (3) > (2) > (1)
C) (1) > (3) > (2)
D) (1) > (2) > (3)
Correct Answer: D
Solution :
Key Idea: Stronger the acid, weaker is its conjugate base. The strength of their conjugate acids are in the order: \[HC\equiv CH>{{H}_{2}}C=C{{H}_{2}}>C{{H}_{3}}-C{{H}_{3}}\] Therefore, the correct order of strength of their conjugate base is: \[C{{H}_{3}}C{{H}_{2}}^{\Theta }>{{H}_{2}}C=\overset{\Theta }{\mathop{C}}\,H>HC\equiv \overset{\Theta }{\mathop{C}}\,\]You need to login to perform this action.
