Chemical Bonding And Molecular Structure Question 31
Question: The table shown below gives the bond dissociation energies $ (E_{diss}) $ for single covalent bonds of carbon atoms with element $ A,B,C $ and $ D. $ Which element has the smallest atoms [CBSE PMT 1994]
| Bond | $ E_{diss},(kJmo{l^{-1}}) $ |
|---|---|
| $ C-A $ | 240 |
| $ C-B $ | 328 |
| $ C-C $ | 276 |
| $ C-D $ | 485 |
Options:
A) A
B) B
C) C
D) D
Show Answer
Answer:
Correct Answer: D
Solution:
Bond dissociation energy decreases with increase in size. So D is smallest.
