• A. Reaction of vinegar and baking soda
• B. Reaction of sodium hydroxide and sulphuric acid
• C. Reaction of hydrochloric acid and potassium hydroxide
  
• D. Reaction of hydrogen and oxygen

Answer 1

The correct option is D Reaction of hydrogen and oxygen

From the given options we can see that
(a) Reaction of vinegar and baking soda which is a reaction of acid and a base which results in formation of salt and water which is a neutralization reaction.
(b) This is also a reaction between acid and base which results in neutralization reaction
(c) This is also a reaction between acid and base which results in neutralization reaction
(d) This is not a neutralization reaction as the reaction is not between acid and base but between two gases(reaction between two nonmetals).
