Write the conjugate acids for the following Brönsted bases: NH₂⁻, NH₃, HCOO⁻
निम्नलिखित ब्रॉन्स्टेड क्षारकों के लिए संयुग्मी अम्ल लिखिए : NH₂⁻, NH₃, HCOO⁻
  1. ANH₃, NH₄⁺, HCOOHNH₃, NH₄⁺, HCOOH
  2. BN³⁻, NH₃, HCO₂⁻N³⁻, NH₃, HCO₂⁻
  3. CNH₄⁺, NH₃, CO₂NH₄⁺, NH₃, CO₂
  4. DMore than one of the aboveउपर्युक्त में से एक से अधिक
  5. ENone of the aboveउपर्युक्त में से कोई नहीं
Show answerHide answer

Correct answer: (A) NH₃, NH₄⁺, HCOOHNH₃, NH₄⁺, HCOOH

Explanation

A conjugate acid is formed by adding a proton: NH₂⁻ + H⁺ → NH₃, NH₃ + H⁺ → NH₄⁺, and HCOO⁻ + H⁺ → HCOOH.संयुग्मी अम्ल प्रोटॉन जोड़ने पर बनता है: NH₂⁻ + H⁺ → NH₃, NH₃ + H⁺ → NH₄⁺ और HCOO⁻ + H⁺ → HCOOH।
