Answer : The required bond energy per mole for breaking all the bonds in methane is, 1656 kJ/mol

Explanation :

The given compound is, [tex]CH_4[/tex].

Methane compound breakdown into 4 C-H bonds.

Given:

[tex]B.E_{C-H}[/tex] = 414 kJ/mol

The expression will be:

[tex]\Delta H_{CH_4}=4\times (B.E_{C-H})[/tex]

[tex]\Delta H_{CH_4}=4\times (414kJ/mol)[/tex]

[tex]\Delta H_{CH_4}=1656kJ/mol[/tex]

Therefore, the required bond energy per mole for breaking all the bonds in methane is, 1656 kJ/mol
