Question

Define the following terms:
(i) diastereoisomer;
(ii) constitutional isomer.

Answer 1

Answer:

(i) diastereoisomer

Diastereomers are stereoisomers that are not related as object and mirror image and are not enantiomers. Unlike enatiomers which are mirror images of each other and non-sumperimposable, diastereomers are not mirror images of each other and non-superimposable. Diastereomers can have different physical properties and reactivity. They have different melting points and boiling points and different densities.

(ii) constitutional isomer

Constitutional isomers are compounds that have the same molecular formula and different connectivity. To determine whether two molecules are constitutional isomers, just count the number of each atom in both molecules and see how the atoms are arranged.

Answer 2

Answer:

1.noun. chem a type of isomer that differs in the spatial arrangement of atoms in the molecule, but is not a mirror image; a stereoisomer that is not an enantiomer. WORD OF THE DAY.

2.Constitutional isomers are compounds that have the same molecular formula and different connectivity. To determine whether two molecules are constitutional isomers, just count the number of each atom in both molecules and see how the atoms are arranged
