The correct Answer is:
To find the conjugate acid of morphine (C₁₇H₁₉NO₃), we can follow these steps:
### Step 1: Identify the Base
Morphine is given as a base with the molecular formula C₁₇H₁₉NO₃. According to the Bronsted-Lowry theory, a base is a substance that can accept a proton (H⁺).
### Step 2: Add a Proton (H⁺) to the Base
To find the conjugate acid of morphine, we need to add a proton (H⁺) to the base. This means we will increase the number of hydrogen atoms in the molecular formula by one.
### Step 3: Calculate the New Molecular Formula
Starting with the original formula of morphine:
- C₁₇H₁₉NO₃
When we add one proton (H⁺), we increase the hydrogen count by one:
- New formula: C₁₇H₁₉NO₃ + H⁺ = C₁₇H₂₀NO₃
### Step 4: Indicate the Charge
Since we have added a proton, the conjugate acid will carry a positive charge. Therefore, the final formula for the conjugate acid of morphine is:
- C₁₇H₂₀NO₃⁺
### Conclusion
The conjugate acid of morphine (C₁₇H₁₉NO₃) is C₁₇H₂₀NO₃⁺.

An organic compound (A) (C_(5)H_(7)OCl) reacts rapidly with ethanol to give (B) (C_(7)H_(12)O_(2)) . (A) also reacts with water to produce an acid which reacts with bromine to give (C ) (C_(5)H_(8)Br_(2)O_(2)) . (B) on boiling with H_(2)SO_(4) forms an acid (D). When (D) is oxidised with KMnO_(4) an acid (E ) (C_(4)H_(6)O_(3)) is produced. On mild heating, (E ) gives (F) (C_(3)H_(6)O) which cannot be oxidised by ammoniacal AgNO_(3) . Identify the compounds (A) to (F).
