I need to explain hwy but-2-en-1-ol has a higher bp.p then 1-bromobut-2-ene
I said they both contain van der walls, and possess dipole-dipole interaction. Cbeing delta positive and the Br delta negative. I said that but-2-en-1-ol has hydrogen bonding and the bromo compund doesnt, and that as the hydrogen bonding is a lot stronger then all the other intermolecular foces, more energy is needed to break the bonds, so therefore it has a stronger boiling point.

Is this correct? (B.P of bt-2-en-1-ol) watch

No bonds are broken when things boil, only intermolecular forces.
So the H-bonds take more energy to break than the vdW forces.
