Question

During the combustion of methane in water, which bonds are broken and which bonds are formed? Sort the molecules based on whether their bonds are broken or formed during the combustion reaction.

Answer 1

Answer:

The bonds which are broken are:-

Bonds of $C-H$ in the $CH_4$

Bonds of $O-O$ in the $O_2$

Bonds which are formed are:-

Bonds of $C-O$ in the $CO_2$

Bonds of $O-H$ in the $H_2O$

Explanation:

The combustion reaction of methane is shown below as;-

$CH_4+2O_2\rightarrow CO_2+2H_2O$

Covalent bond is the bond which is formed with the sharing of the electrons between the two atoms which are taking part in the bond. It is generally formed between the atoms with similar electronegativity values. All the bonds in the above equation are covalent bonds.

The bonds which are broken are:-

Bonds of $C-H$ in the $CH_4$

Bonds of $O-O$ in the $O_2$

Bonds which are formed are:-

Bonds of $C-O$ in the $CO_2$

Bonds of $O-H$ in the $H_2O$
