Arrange the following in the correct order of decreasing bond enthalpy
As we learnt
Carbon halogen (C-X) bond length, Bond enthalpy and dilpole moments -
These factors depends of nature of C-X bonds.
- wherein
In haloalkanes bond strength of carbon-halogen bond decreases with an increase in bond length, as one moves from fluorine to iodine.So the order will be
Therefore, option (1) is correct.
