Question

structure of 1,2 dichloro ethane into ethyne

​

Answer 1

Answer:

Ethyne to 1,2 dichloroethane

CH=CH + 2HCI + CHCI, - CH3

Answer 2

$CH2_{2} ClCH2_{2} Cl$ → $CH_{2}$=$CH_{2}$ → $CH$≡$CH$

• Dichloroethane $CH2_{2} ClCH2_{2} Cl$ turns into $CH_{2}$=$CH_{2}$ (ethene) due to the action of $Cl_{2}$ / $CCl_{4}$
• The ethene then becomes ethyne $CH$≡$CH$ with the help of $H_{2}$ / $PdBaSO_{4}$
