Concept explainers
(a)
Interpretation:
The group number of the nitrogen should be determined according to the periodic table and whether the group number is matched with the number of dots on nitrogen in Figure 2.1 should be checked.
Concept Introduction :
In the periodic table, elements are arranged in order of increasing
Nitrogen present in the fifth column and the second period of the periodic table.
(b)
Interpretation:
The number of line bonds that are attached to
Concept Introduction :
A number of line bonds indicate the number of line bonds to the atom in the Lewis structure.
(c)
Interpretation:
Number of nonbonded electrons drawn on
Concept Introduction :
The number of nonbonded electrons are free electrons that can be seen on the atom in the Lewis structure. These are shown by using dots on the atom.
(d)
Interpretation:
The formal charge of each atom in
Concept Introduction :
Formal Charge = Group Number − Number of lines − Number of dots
Group Number refers to the column number on the periodic table.
The number of lines indicates the number of line bonds to the atom in the Lewis structure or it shows the number of bonded pairs of electrons.
Number of dots represent the number of non-bonded electrons on an atom in the Lewis structure

Organic Chemistry: A Guided Inquiry
- Please help me with this, I have attached two images which are incorrect answers, I now want to study, lone pairs DO NOT MATTER, only charge and structure.arrow_forwardI got this marked wrong on an assignment, but I'm not sure why. Please help me find the correct resonance structure.arrow_forwardConsider Lewis formulas A, B, and C:(a) Are A, B, and C constitutional isomers, or are they resonance contributors? (b) Which have a negatively charged carbon? (c) Which have a positively charged carbon? (d) Which have a positively charged nitrogen? (e) Which have a negatively charged nitrogen? (f) What is the net charge on each? (g) Which is a more stable structure, A or B? Why? (h) Which is a more stable structure, B or C? Why? (i) What is the CNN geometry in each according to VSEPR?arrow_forward
- can someone explain how Molecule B has a tertiary carbon ? Im having troubl with secondary and tertiary i tried to calculate the formal charges thinking that may have something to do with it but I ended up getting the wrong formal charge for molecule B, so now I'm confused.arrow_forwardWhy are the two resonance structures I circled in green incorrect? My professor's answer key is the picture with the red text.arrow_forwardIt keeps saying my answer is wrong, but I do not understand why with the structure they gave me to work with. If I try to add a double bond to N it says both N and O have valence issuesarrow_forward
- Hi can you please help with with questions 2 and 8. Thank you so much! 2. What is the molecular formula of your mononitrated reaction product? 8. Based on all of the data provided, what is the identity of the “G” group? Please NEATLY & CLEARLY draw its full Lewis structure in the space providedarrow_forwardConsider this “Dr. Yan’s imaginary” molecule below in line-angle formula. Note that you MAY NOT add or remove lone pairs. How many CH groups are there in the molecule? ____________ b) The formal charge of O is:__________; and the formal charge of N is: ____________________ c) The overall charge of the molecule: ___________arrow_forwardIn order to determine high and low electron density, is it necessary to include minor resonance structures? The textbook answer says 'significant resonance contributors suggest the areas of highest and lowest electron density.' Does this mean minor structures are also significant?arrow_forward
- Some of the figures below represent invalid sets of resonance structures for this molecule.arrow_forwardAssign the correct formal charge to the oxygen atom in this structure (you may right click on the atom and use the Charge menu, or use the + and - buttons on the graphical toolbar). Once the correct formal charges have been placed, identify all atoms with a reasonable formal charge by setting the map number to 1, and those with an unreasonably large formal charge by setting the map number to 2. HINT: all of the hydrogen atoms are already shown.arrow_forwardDraw the lewis structure of SO2 ( best resonance) and 2nd best resonance showing the shape and bond angles of each one, the 3D structure with polar bonds or bonds dipole of each one and the molecular polarity. Here is an example of what I want the answer to be like:arrow_forward
