Concept explainers
(a)
Interpretation:
The orbital picture of ammonium ion indicating the important overlap of AOs is to be drawn.
Concept introduction:
According to the
(b)
Interpretation:
The energy diagram of ammonium ion indicating the formation of molecular orbitals (MOs) is to be drawn.
Concept introduction:
The molecular orbitals are formed by overlapping of atomic orbitals of adjacent atoms. The numbers of molecular orbitals formed are equal to the number of atomic orbitals that overlap. The two atomic orbitals, on mixing along bonding axes, form two molecular orbitals; one is

- I'm very confused on this. please help thank youarrow_forwardEvery box should contain two structures. Be sure to include all lone pair electrons and nonzero formal charges. Step 1 Step 2 Step 3 Step 4 Draw H3O*, and then add the curved arrow notation showing an electrophilic addition of H*.arrow_forwardProblem (#2.) For each ion below, draw all reasonable resonance structures (linked by resonance arrows “↔”). Include curved arrows that indicate the movement of electrons between each resonance structure. Assign non-zero formal charges to each atom for each resonance structure. (a.) NO3– (nitrate) (b.) CH3COO– (acetate) (c.) N3– (azide) (d.) NCO– (isocyanate) Problem (#3.) For each ion in question 2, draw a resonance hybrid, assigning non-zero formal and/or partial charges (δ+, δ–) as needed. Problem (#4.) For each skeletal structure below, satisfy the valences (or octets) of all of the atoms by filling in double and triple bonds as well as unshared electron pairs. Assign non-zero formal charges and show the overall charge if the structure is an ion. See photo attached for Problem number 4. Problem (#5.) For each structure in question 4, draw a resonance hybrid (if it has one) and assign non-zero formal and/or partial charges as needed.arrow_forward
- Predict the highlighted C–C bond that has the lowest BDE (weakest bond).arrow_forwardPlease construct a I -C-E table.arrow_forwardFor 1 and 2, use curved arrows to illustrate the potential overall electron movements or bond changes, and identify the type of reaction by examining the overall chemical transformation. Show A-H bonds as needed.arrow_forward
- The next part of the problem is to draw the resonance hybrid. (Exclude formal charges) I’m not sure where to put the dotted resonance lines of the hybrid structure.arrow_forwardExamine the molecule below, and select the statements that apply. If it can lose H, draw its conjugate base. If it can gain H', draw its conjugate acid. Show all lone pairs and non-zero formal charges. NH OThis molecule will not lose an H O This molecule will not gain an H" O This molecule could lose an H*. Its conjugate base is: O This molecule could gain an H". Its conjugate acid is:arrow_forwardSolve correctly please, need all 4 subparts ans.arrow_forward
- A. Determine whether the curved arrow(s) shown below generate a valid or invalid resonance structure. Draw the resonance structure that would result from each properly drawn arrow and identify the arrow pushing pattern (i.e. allylic positive charge, allylic lone pair, pi bond between atoms of a different electronegativity, lone pair adjacent to a positive charge, alternating pi bonds in a ring.arrow_forwardPlease draw a more stable resonance structure for the following molecule. Use a curved arrow to show how to transform the original structure to the new one and please specify charges.arrow_forwardA. в. с. Figure 4-8 D. СН3 0: сн.
