Concept explainers
(a)
Interpretation:
From the condensed structures for 2,3-dimethyl-2-pentene whether cis-trans isomers exist or not has to be given. And if it exists, both the isomers has to be drawn.
Concept Introduction:
Condensed structures: A condensed structures only shows the total number of atoms but not bonds exist between the atoms. The vertical and horizontal line which represents bonding all should be omitted.
Line structure: In organic compounds, the series of atoms in the compound are bonded together which shown by drawing a line between them. End of line segment represents carbon
Predicting cis-trans isomers:
In general, the
Cis-isomer: In cis-configuration, the two bulkier substituents of the double bond are on the same side.
Trans-isomer: In trans-configuration, the two bulkier substituents of the double bond are on the opposite side.
(b)
Interpretation:
From the both condensed and line structures for 2-Methyl-2-hexene whether cis-trans isomers exist or not has to be given. And if it exists, both the isomers has to be drawn.

- Drawn are four isomeric dimethylcyclopropanes. How are the compounds in each pair related (enantiomers, diastereomers, constitutional isomers): A and B; A and C; B and C; C and D?arrow_forwardWhen Alfred Werner was developing the field of coordination chemistry, it was argued by some that the optical activity he observed in the chiral complexes he had prepared was due to the presence of carbon atoms in themolecule. To disprove this argument, Werner synthesized a chiral complex of cobalt that had no carbon atoms in it, and he was able to resolve it into its enantiomers. Design a cobalt(III) complex that would be chiral if it could be synthesized and that contains no carbon atoms.arrow_forward(A) What are Waxes? Draw the structure of wax, which is made up of palmitic acid (16:0) and a saturated 18-carbon alcohol. (В) Consider the structure of menthol. How many isoprene units are present in menthol? (C) What type of isoprene linkage (head-to-tail or tail-to-tail) is present in menthol? Identify the isoprene linkage in the following structure of menthol and indicate by a circle. Menthol =arrow_forward

Chemically, spermaceti is cetyl palmitate, the ester of palmiticacid with cetyl alcohol (the straight-chain 16-carbon alcohol). Draw the structure of spermaceti.arrow_forwardHow many optical isomers (stereoisomers) are possible for the above amino acid (aqueous form)?
