Given below are two statements; one is labelled as Assertion (A) and the other is labelled as Reason(R).
Assertion : The alkyldiazonium salt are unstable but the arenediazonium salt are stable for a short time at low temperature ((0^{\circ}-5^{\circ} \mathrm{C}))
Reason : Due to resonance in arenediazonium salt carbon-nitrogen bond becomes stronger than alkyldiazonium salt.
In the light of the above statements, choose the most appropriate answer from the options given below :
Options
- ABoth (A) and (R) are correct and (R) is the correct explanation of (A).
- BBoth (A) and (R) are correct but (R) is not the correct explanation of (A).
- C(A) is correct but (R) is not correct.
- D(A) is not correct but (R) is correct.
Correct answer
A. Both (A) and (R) are correct and (R) is the correct explanation of (A).
Step-by-step solution
Assertion (A):
The alkyldiazonium salts are unstable but the arenediazonium salts are stable for a short time at low temperatures (\left(0^{\circ}-5^{\circ} \mathrm{C}\right)).
This statement is correct. Alkyldiazonium salts tend to decompose rapidly, while arenediazonium salts can be relatively stable at low temperatures for a short period.
Reason (R):
Due to resonance in arenediazonium salt, the carbon-nitrogen bond becomes stronger than in alkyldiazonium salt.
This statement is also correct. The resonance stabilization in arenediazonium salts does contribute to the stability of the carbon-nitrogen bond compared to that in alkyldiazonium salts.
Conclusion:
Both the assertion and reason are correct. However, the reason provides a valid explanation for the assertion.
The most appropriate answer is: (1) Both (A) and (R) are correct and (R) is the correct explanation of (A).
