Question

4.
c) greater in ethene
The C- C bond energy order in ethane, ethene and ehtyne is
a) Ethyne < ethene < ethane
b) Ethene < ethane < ethyne
c) Ethyne > ethene > ethane
d) Ethane < ethyne < ethene​

Answer 1

Answer:

d is the correct option

Explanation:

this is easy chapter I think sooo

Answer 2

Answer:

C−H bond energy in ethane =410kJ/mol

C−H bond energy in ethene =451kJ/mol

C−H bond energy in ethyne =536kJ/mol

So, C−H bond energy in ethyne is maximum.

Note: H attached to more electronegative C has more bond energy.

so, option c is the correct one

hope it helps you ✨✌
