Concept explainers
(a)
Interpretation:
The following pair of molecules should be classified as stereoisomers, constitutional isomers, or identical molecules:
Concept Introduction:
Isomers are the compounds having same molecular formula but different structure. The phenomenon possessed by the molecules is known as isomerism.
Compounds having same molecular formula but possessing different connectivity of atoms or group of atoms are known as constitutional isomers.
The compounds which have same molecular formula, same connectivity of bond but the arrangement of atoms in space is different are known as stereoisomers.
The compounds having same bond connectivity and same molecular formula are known as identical molecules.

- Draw the staggered and eclipsed conformations that result from rotation around the C–C bond in CH3–CH2Br.arrow_forward3. occur when molecules change shape due to the rotation of atoms around single bonds. Conformations Stereoisomers Structural isomers Positional isomersarrow_forwardOrganic compounds may have characteristic odors as well as other characteristic physical properties. For example, the distinct odor of the seashore at low tide results in part from the presence of dimethyl sulfide (CH3SCH3), a molecule with a similar structure to dimethyl ether (CH3OCH3). Ethanethiol (CH3CH2SH), also called mercaptan, is an isomer of dimethyl sulfide with a much less pleasant odor.The table lists four related compounds and their enthalpies of vaporization (ΔH°vap) in kJ/mol.

Place the compound with the strongest intermolecular forces (IMFs) at the top of the list. (Strongest to weaknest). Why is ΔHºvap for CH3SCH3 greater than ΔHºvap for CH3OCH3? A. CH3OCH3 is more polar. B. CH3SCH3 has stronger dipole–dipole attractions. C. CH3OCH3 can form…arrow_forward
