The correct order of increasing bond length of C-H C-O C-C and C=C is C-H < C=C < C-O < C-C C-C < C=C < C-O < C-H C-O < C-H < C-C < C=C C-H < C-O < C-C < C=C
Multiple Choice Options
- A 9.08
- B 9.43
- C 11.72
- D 8.73
Step-by-Step Verified Solution
pOH = pK b + log [ S a l t ] [ B a s e ]
= � log K b + log [ S a l t ] [ B a s e ]
= � log 1.8_ 10 �5 + log 0.20 0.30
= 5 � 0.25 + (�0.176) = 4.57
Now, pH = 14 � pOH = 14 � 4.57 = 9.43
