Question

What is the special feature of the structure of (i) ethene (ii) ethyne

Answer 1

i. H₂C = CH₂ (Ethene)

Ethene contains a double bond. In ethene, the two carbon atoms form a double bond.

ii. HC ≡ CH (Ethyne)

The C ≡ C bond is very strong due to the presence of two π bonds, making ethyne more reactive than ethane.
