Question

Assertion: $C{l}^{-}$ is the conjugate base of HCl.
Reason: A conjugate base is formed once a Bronsted-Lowry acid accepts a proton.

• A. Both Assertion and Reason are true and Reason is the correct explanation of Assertion
  
• B. Both Assertion and Reason are true but Reason is not the correct explanation of Assertion
• C. Assertion is true but Reason is false
• D. Assertion is false but Reason is true
• E. Both Assertion and Reason are false

Answer 1

Answer: (C)

Assertion is true but Reason is false

Assertion: $C{l}^{-}$ is the conjugate base of HCl.
Reason: A conjugate base is formed once a Bronsted-Lowry acid donates a proton
$HCl\to H^{+}+C{l}^{-}$
Thus, an acid and its conjugate base differ by a proton.
Assertion is correct but Reason is not correct.
