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

Explanation :

The given compound is,
CH_4 .

Methane compound breakdown into 4 C-H bonds.

Given:

B.E_(C-H) = 414 kJ/mol

The expression will be:

$\Delta H_(CH_4)=4* (B.E_(C-H))$

$\Delta H_(CH_4)=4* (414kJ/mol)$

$\Delta H_(CH_4)=1656kJ/mol$

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