(a)
(b)
(c)

For each of the following molecules, draw one 3-D representation at only the necessary atoms (that is, the ones with four different atoms/groups attached).

(b)

Give the relationships between the following pairs of structures. The possible relationships are as follows: same ­compound, cis-trans isomers, constitutional (structural) isomers, and not isomers (different molecular formula).

(a) CH₃CH₂CH₂CH₃ and (CH₃)₃CH

(b) CH₂=CH–CH₂Cl and CHCl=CH–CH₃

For each pair of structures, determine whether they represent different compounds or a single compound.
