When C2H2, CH4 and C2H4 pass through a test tube which have ammoniacal Cu2Cl2, find out which gas comes out unaffected from test tube?

Question

When C2H2, CH4 and C2H4 pass through a test tube which have ammoniacal Cu2Cl2, find out which gas comes out unaffected from test tube? (A) C2H2 and CH4 (B) C2H2 and C2H4 (C) C2H4 and CH4 (D) C2H2

Alkynes, containing terminal H-atom, reacts with ammoniacal Cu2Cl2 solution. So, C2H2 reacts with ammoniacal Cu2Cl2 solution while CH4 and C2H4 remain unaffected HC ≡ CH ->[ textAmmoniacal][Cu2Cl2] CuC≡ CCu

Q. When $C_{2} H_{2}, C H_{4}$ and $C_{2} H_{4}$ pass through a test tube which have ammoniacal $C u_{2} C l_{2}$ , find out which gas comes out unaffected from test tube?

$C_{2} H_{2}$ and $C H_{4}$

$C_{2} H_{2}$ and $C_{2} H_{4}$

$C_{2} H_{4}$ and $C H_{4}$

$C_{2} H_{2}$

Alkynes, containing terminal $H$ -atom, reacts with ammoniacal $C u_{2} C l_{2}$ solution. So, $C_{2} H_{2}$ reacts with ammoniacal $C u_{2} C l_{2}$ solution while $C H_{4}$ and $C_{2} H_{4}$ remain unaffected
$H C \equiv C H Ammoniacal C u_{2} C l_{2} C u C \equiv CC u$
