Interpretation:
The orbital overlap picture of But-1-ene-3-yne is to be drawn and reason of delocalization of one (-bonds in triple bond and localization of one (-bonds is to be discussed.
Concept introduction:
In chemistry, overlapping of orbital takes place to form bonds between the atoms. At least two orbitals must overlap with each other to form a bond. The examples of orbitals are s, p, d, f orbitals.Sigma bond involves the head to headoverlapping of two orbitals; on the other hand, pi bond involves the side to side or lateral overlapping of two orbitals.
The lone pairs are unpaired electron present in the orbitals of the atom.Oxygen has two pairs of lone pair.
The localized lone pair is the lone pair which is present in the hybrid orbital and does not take part in resonance.
On the other hand, delocalized lone pair is the lone pair which is present in non-hybrid orbital and does take part in resonance.

- Given the following two negatively charged molecules. Draw in the pi orbitals. In which of the two molecules is the negative charge the most stabilized. WHY???arrow_forwardHCN is a molecule with ["1", "2", "3", "4"] electron domains giving it a ["trigonal planar", "linear", "tetrahedral"] electron domain geometry. It has ["3", "4", "2", "1"] bonded atoms and ["0", "3", "1", "2"] lone pairs. HCN will exhibit a ["bent", "linear", "trigonal planar", "tetrahedral", "trigonal pyramidal"] molecular geometry.arrow_forwardThe molecule shown on the right in the example in the right column is the amino acid histidine, and the five-membered ring is known as aromatic. An aromatic ring has 2, 6, 10, 14, etc., electrons placed in 2p orbitals around a ring. Indicate which of the following statements must therefore be true. 1. There are a total of six electrons in the pi system (defined as electrons in 2p orbitals), including the lone pair on the ring N that is not circled. 2. There are a total of six electrons in the pi system, including the lone pair on the ring N atom that is circled. 3. The lone pair on the ring N atom that is not circled resides in an sp2 orbital on an sp2 hybridized nitrogen atom. 4. Statements 2 and 3 are both truearrow_forward
- 1. Neatly draw the Lewis dot structure. (Must be hand-drawn and very neat) 2. Count and report the number of electron regions around the center atom. 3. Count and report the number of bonds around the center atom. 4. Draw the i ground state ii. Promoted state and iii. Hybrid state energy level diagrams for the center atom 5. Neatly draw the molecule in three dimensions showing atomic/hybrid orbital overlap demonstrated in the figure above. 6. Label all bond angles.

Explain that Energy levels of the atomic orbitals and what kind of character the bonding and antibonding orbitals display.arrow_forward4. ,A: Briefly describe why the p orbital can contain a positive charge and hybridized orbital cannot. Use pictures in your answer. B: Briefly explain why a hybridized orbital can contain a negative charge, and P-orbital cannot. Use pictures in your answer.arrow_forwardTrue or false? 1) In electron sea model, all the electrons of the contributing atoms are delocalized in the array of metal atoms and are involved in metallic bonding. 2) In molecular orbital theory, the no. of molecular orbitals formed is twice the no. of atomic orbitals used in the formation of the molecular orbitals. 3) Resonance structures of the same compound can have different arrangement of atoms.arrow_forward
- Given the molecule CH2CHCN Please draw a Lewis structure for this compound with CORRECT GEOMETRY and label all sigma and pi bonds with the orbitals it is made from (what orbitals are overlapping to form the bond). You may draw the hybridized sigma orbitals as sticks and the unhybridized p-orbitals as lobes for clarity. For this question, you DO need to draw out the orbitals.arrow_forwardWhich best describes the resonance hybrid for the following molecule? .N. The electron deficiency is delocalized exclusively over the two carbon atoms (CH* and the CHN). The central atom (the N atom) will be neutral. O The electron deficiency is localized exclusively on the N atom. The electron deficiency is delocalized exclusively over the two atoms (CH* and the N atom).
