Question

Match the following bond enthalpies with their respective bonds: 

• A. A-II, B-III, C-I, D-IV
• B. A-II, B-IV, C-III, D-I
• C. A-III, B-I, C-I, D-IV
• D. A-III, B-I, C-IV, D-II

Hint:

Bond enthalpy is a measure of bond strength. Typically, C-C bonds have the highest enthalpy among Group 14 elements.

Answer 1

The Correct Option is A

Step 1: Identifying bond enthalpies of the given bonds
- Silicon-Silicon (\( Si-Si \)) bond enthalpy = 240 kJ/mol.
- Carbon-Carbon (\( C-C \)) bond enthalpy = 348 kJ/mol.
- Tin-Tin (\( Sn-Sn \)) bond enthalpy = 297 kJ/mol.
- Germanium-Germanium (\( Ge-Ge \)) bond enthalpy = 260 kJ/mol.
Step 2: Matching the correct bond enthalpies
Comparing with the given data: \[ Si-Si \rightarrow 240 \quad (II), \quad C-C \rightarrow 348 \quad (III), \quad Sn-Sn \rightarrow 297 \quad (I), \quad Ge-Ge \rightarrow 260 \quad (IV) \]
Thus, the correct match is: \[ A-II, B-III, C-I, D-IV \]
