The bonds that break in this reaction are one C=C bond and four C-H bonds.
In the combustion of ethene, the pi bonds between the carbon atoms in the double bond are broken first. This is followed by breaking the sigma bonds between the carbon and hydrogen atoms. Finally, the bonds between carbon and oxygen atoms in the formed carbon dioxide molecules are also broken.
When ethene (C2H4) burns in the presence of oxygen, it undergoes combustion to produce carbon dioxide (CO2) and water (H2O) as byproducts. The combustion reaction typically releases heat and light energy.

Bonds are broken during chemical reactions when energy is input to overcome the attractive forces between atoms that hold them together. This can happen in various situations, such as in a combustion reaction when fuels are burned or in a biochemical reaction during metabolism.
In the combustion of methane with oxygen, the bonds broken are the C-H bonds in methane and the O=O bonds in oxygen. New bonds form, which are primarily the C=O bonds in carbon dioxide and the O-H bonds in water.
Both ethane and ethene have the same number of carbon atoms per molecule, which is two. However, the difference lies in the type of bonds between the carbon atoms - ethane has single bonds, while ethene has a double bond.
All four C-H bonds in methane are broken during combustion.
During the combustion of methane (CH4) to form water (H2O) and carbon dioxide (CO2), the bonds broken are the carbon-hydrogen (C-H) bonds in methane and the oxygen-oxygen (O=O) bonds in molecular oxygen (O2). These bonds are broken to form new bonds between carbon and oxygen in CO2, and hydrogen and oxygen in H2O.

the bond broken are C-H bonds (in methane) and O-O bonds (in oxygen) The reaction is :- CH4 +2O2 -> CO2 + 2H2O
methane is a gas
