Concept explainers
(a)
Interpretation:
The molecule which has a handedness to it and can exist in two mirror-image forms has to be identified and the reason has to be given.
Concept Introduction:
Chiral: An object that is not super imposable on its mirror image which means that they show handedness.
Achiral: An object having super imposable mirror images or lacking chirality.
Plane of symmetry: It is an imaginary plane passing through an object which divides the object into two mirror images.
(b)

General Chemistry: Atoms First
- Can these be convertible to one another through ring flips? What type of relationship do the two have? Which has higher potential energy, why?arrow_forwardA _____________________ occurs when there are two ormore alternate structures of a molecule that differ in theposition of electrons.arrow_forwardThe absolute configuration of (−)-bromochlorofluoromethane is R. Which of the following is (are) (−)-BrClFCH?arrow_forward
- The terms configuration and conformation appear in descriptions of molecular structure. How do they differ?arrow_forwardThree resonance structures are possible for dinitrogen monoxide, N2O. (a) Draw the three resonance structures. (b) Calculate the formal charge on each atom in each resonance structure. (c) Based on formal charges and electronegativity, predict which resonance structure is the most reasonable.arrow_forward(a) Sketch the occupied MOs of the valence shell for the N2 molecule. Label the orbitals as or orbitals, and specify which are bonding and which are antibonding. (b) If one electron is removed from the highest occupied orbital of N2 , will the equilibrium NN distance become longer or shorter? Explain briefly.arrow_forward
- What is the rough hybridization of the carbon orbitals in the methyl carbonium ion, CH3+, which is almost perfectly planar triangular in shape?arrow_forwardExplain why 1g is the ground state for H2+ . By combining your answer with the answer to Problem 5, what conclusions can you draw about the molecular orbital description of the bond in H2+ ?arrow_forwardAll carbon-to-carbon bond lengths are identical in benzene. Does this argue for or against the presence of C=C bonds in benzene? Explain.arrow_forward
- Both the HCH and HCO bond angles of H2CO (formaldehyde) are very close to 120°, but oneis slightly smaller than the other. Predict which is smaller, and explain your reasoning.arrow_forwardWhich nitrogen in the following molecules can more readily interact with an electron poor atom through its nonbonding electrons? Explain by drawing a molecular orbital "cartoon" for each molecule to determine where those nonbonding electrons reside. Use a few words too, to help your explanation.arrow_forward(a) How does the structure of diborane (B2H6) differ fromthat of ethane (C2H6)? (b) Explain why diborane adoptsthe geometry that it does. (c) What is the significance ofthe statement that the hydrogen atoms in diborane aredescribed as “hydridic”?arrow_forward
