Match the column:- ( array |l|l|l|l| & Column-I & & Column-II & (Reactants) & & (Products) (a) & CaC ₂+ H ₂ O & (p) & CaC ₂ (b) & CaO + C & (q) & H ₂ (c) & HC CH + Na & (r) & CH ₄ (d) & array l CH ₃ COOH + NaOH + CaO array & (s) & C ₂ H ₂ array )

Options

  1. Aa-q, b-p, c-r, d-s
  2. Ba-p, b-q, c-s, d-r
  3. Ca-s, b-p, c-q, d-r
  4. Da-p, b-q, c-r, d-s

Correct answer

C. a-s, b-p, c-q, d-r

Step-by-step solution

Here's the matched column: (a) ( CaC ₂+ H ₂ O Ca ( OH ) 2+ C ₂ H ₂( s ) ) (b) ( CaO +3 C CaC ₂ ) (p) +CO (c) ( HC CH +2 Na Na ₂ C ₂+ H ₂ ) (q) (d) ( CH ₃ COOH + NaOH + CaO CH ₄( r )+ Na ₂ CO ₃+ CaCO 3 ) So, the correct answer is: (4) (a-s, b-p, c-q, d-r ) Explanation: - (a) Calcium carbide reacts with water to produce acetylene (( C ₂ H ₂) ). - (b) Calcium oxide reacts with carbon to produce calcium carbide. - (c) Acetylene reacts with sodium to produce sodium acetylide and hydrogen gas. - (d) Sodium hydroxide and
