General Chemistry Challenge Problem: Molecular Geometry and Bonding Theories A compound composed of 2.1% H, 29.8% N, and 68.1% O has a molar mass of approximately 50g/mol. (A). What is the molecular formula of compound? (B). What is its Lewis structure if H is bonded to O? (C). What is the geometry of the molecule? (D). What is the hybridization of the orbitals around the N atom? (E). How many sigma and how many pi bonds are there in the molecule?

What do you think the first step is here?

I know the answer. I want to see if you know. You can just tell me the steps. Free medal and fan.

(A) Oh ok well to find the molecular formula just take integer multiples of the masses of each specific element and divide by 50 then multiply by x100 to find your percentage value if it matches up you have the right molecular formula i believe this comes out to HNO2

Yes, that is correct. Element grams given x(mol/actual gram)

(B) |dw:1439532802139:dw| Lewis structure is this i thnk
sweetburger
  • sweetburger
2 lone pairs on each oxygen
sweetburger
  • sweetburger
(C) The geometry would be im assuming bent but that hydrogen is throwing me off.
sweetburger
  • sweetburger
forgot the lone pair on the nitrogen in the lewis structure
sweetburger
  • sweetburger
kind of important
sweetburger
  • sweetburger
(D) 3 areas of electron density so im pretty sure sp2 hybridization
sweetburger
  • sweetburger
(e) So there would be 3 sigma bonds and 1 pi bond

so did i get them right?

B) is correct. C) yea they just want the electron domain. Oops forgot to tell you. Is it trigonal planar or tetrahedral? D) is correct E) is correct
anonymous

electron domain geometry*
sweetburger
  • sweetburger
ahh that suddenly makes a lot of sense
anonymous
  • anonymous
Which of the 2 do you think it is?
anonymous
  • anonymous
Trigonal planar and tetrahedral both have bent as their molecular geometry.
sweetburger
  • sweetburger
I think it is trigonal planar due it only having 1 lone pair, but my knowledge of this has become quite rusty.
anonymous
  • anonymous
Yea it is. It has 3 electron domains on the central atom N.
sweetburger
  • sweetburger
and it actually fits a trigonal planar geometry if you look at it.
anonymous
  • anonymous
Not 4 because H is not bonded to N. Nice job! All correct!

alrighty cool :P

i mean i didnt google that question and sure sounds good

id rather make a mistake and learn from what i miss

Yea, I know you did not because you had a fast response rate and I picked the one that I could not find in Google lol.
