Question

What intermolecular forces are present in a sample of FCOH?

Answer 1

in FCOH molecules present

i) london dispersion force

ii)dipole-dipole intraction

iii) hydrogen bonding

i) london dispersion force -  london dispersion force present in all type of molecule it is temporary attractive force magnitude of this force is very weak.

ii)dipole-dipole intraction - in this molecule F and O are more electronegative than carbon therefore attract bonded electron pair more itself and get slightly negative charactor and attract slighly possitive charactor of carbon of diffrent molecule therefore dipole-dipole intraction in this molecule

iii) hydrogen bonding - more electronegative atom F and O form hydrogen bond with other molecule's hydrogen.
