Current Question (ID: 10835)

Question:
$\text{The correct increasing order of C-C bond length is:}$
Options:
  • 1. $\text{C}_2\text{H}_6 > \text{C}_2\text{H}_4 > \text{C}_6\text{H}_6 > \text{C}_2\text{H}_2$
  • 2. $\text{C}_2\text{H}_2 < \text{C}_2\text{H}_4 < \text{C}_6\text{H}_6 < \text{C}_2\text{H}_6$ (Correct)
  • 3. $\text{C}_2\text{H}_6 > \text{C}_2\text{H}_2 > \text{C}_6\text{H}_6 > \text{C}_2\text{H}_4$
  • 4. $\text{C}_2\text{H}_4 > \text{C}_2\text{H}_6 > \text{C}_2\text{H}_2 > \text{C}_6\text{H}_6$
Solution:
$\text{Hint: Bond length is inversely proportional to bond order.}$ $\text{As the C-C bond order increases the C-C bond length is decreases.}$ $\text{The bond order in } \text{C}_2\text{H}_2 \text{ is three, the bond order in } \text{C}_2\text{H}_4 \text{ is 2, } \text{C}_2\text{H}_6 \text{ is 1, and the bond order in } \text{C}_6\text{H}_6 \text{ is 1.5.}$ $\text{As bond order decreases, bond length increases.}$ $\text{Hence, the correct order is } \text{C}_2\text{H}_2 < \text{C}_2\text{H}_4 < \text{C}_6\text{H}_6 < \text{C}_2\text{H}_6$
