Question

17(iii) Assertion: Ethene is an unsaturated hydrocarbon.
Reason: Ethene contains carbon-carbon triple covalent bond.​

Answer 1

Answer:

this is your answer bro

Answer 2

Answer:(1) Ethylene (CH2=CH2) contains a double bond between carbon atoms. (2) Thus, the valencies of the two carbon atoms are not fully satisfied by single covalent bonds. Hence, ethylene is an unsaturated hydrocarbon.

Explanation:to make you understand better ethylene is also called ethene which we know is from the family of alkenes hence its unsaturated and its formula is C2H4 therefore it is a hydrocarbon hence assertion is true. but it forms double bonds instead of triple bonds therefore the reason is false
