    can someone explain what is meant by a planar structure?? i thought its where alll the angles of the molecule are 120 but it says methanoic acid has a planar structure but it has a 104.5 bond angle :/

    q2 does replacing the H in a c-H bond with a halogen make the bond stronger or weaker?? is it stronger due to larger difference in electronegativity????

    All of the atoms are in a plane.

    Same plane, i.e. they're flat. All angles don't have to be 120^{\circ}, no. That's only the case when the molecule is trigonal planar.

    ohhhh.. so from the bond angles how can we tell if it has a planar structure or not?
