    Lewis structures and VSEPR theory
    Consider the following molecules or ions: ClOF3, XeO3, BrO2
    +, and BrOF5. Answer the following
    Questions based on the Lewis structures and VSEPR theory prediction of their molecular shapes.
    (a) Which one has only bond angles of 109.5°?
    (b) Which one has only bond angles of 120°?
    (c) Which one has bond angles of 90 and 180°?
    (d) Which one has bond angles of 90, 120, and 180°?

    Periodic trends and electronegativity
    Consider the four compounds NF3, NCl3, NBr3, and NI3. Use periodic trends in bond lengths and the electronegativity table to answer the following questions:
    (a) Which molecule is expected to have the longest bonds?
    (b) Which molecule is expected to have the most polar bonds?
    (c) Which molecule is expected to have the least polar bonds?

    I would appreciate it if someone helps me
    Thank you

    In answer to your other posts as well, we do not assist with homework. It is in our forum basics. Sorry,

    I'll do the first one:

    Attachment 26547

    Since there are no lone pair of electrons, the shape is tetrahedral.
    However, I don't know the rules about hybridization, so, I would have guessed:

    [Kr] 5s2, 4d10, 5p6, 5d10, 4f4
