A) \[{{C}_{2}}{{H}_{2}}\]
B) \[{{C}_{2}}{{H}_{4}}\]
C) \[{{C}_{2}}{{H}_{4}}B{{r}_{2}}\]
D) \[{{C}_{6}}{{H}_{6}}\]
Correct Answer: C
Solution :
As the 5-character or number of \[\pi -\]electrons increases, bond length decreases. Therefore, \[{{C}_{2}}{{H}_{4}}B{{r}_{2}}\]due to the absence of \[\pi -\]electrons or due to the presence of lesser s-character (25%), has the longest C?H bond distance.You need to login to perform this action.
