Methyl nitrate, CH3NO3，is used as a rocket propellant. The skeleton structure of the molecule is CH3ONO2: The N and three O atoms lie in the same plane, but the CH3 group is not in the same plane as the NO3group. The bond angle C-O-N is 105° and the bond angle O-N-O is 125°, One N-to-O bond length is 120pm and the other two are 136 pm each. a. Draw a Lewis structure of the molecule showing its geometrical shape.

b. Describe the bonding scheme and the probable atomic (including hybrid) orbitals
involved.
c. Explain why all three N-to-O bond lengths are not the same.
d. Is the specie a polar molecule? If so, show the direction of the net dipole.

Do you have any options?

First up write the aim
then write the materials reqd.
then the procedure which you follow
then observation
then conclusion
then you can write lab safety rules or precautions(you can avoid if u want).
lemme' give an example
aim: to observe the double displacement reaction
materials reqd: bacl2 and na2so4, test tubes and a dropper
procedure:
1. take bacl2 in a test tube and na2so4 in the other.
2. then pour bacl2 into na2so4 solution.
3. observe
observation:
you will see that a white precipitate is formed called baso4. along with that common salt or nacl is formed.
the equation is
bacl2+na2so4=baso4+2nacl
conclusion:
a double displacement reaction is observed.
hope it
