Isomers

Question 1

isomers

Answer 1

compounds with the same molecular formula but different arrangements of atoms in the molecule and so, different properties

Question 2

structural isomers (constitutional isomers)

Answer 2

have the same number and type of atoms (same molecular formula) but a different structure (atoms joined differently

Question 3

geometric isomers (cis-trans isomers)

Answer 3

can occur in molecules where a C=C double bond prevents any rotation about the bond. If each C of the C=C bond has two different groups or atoms attached, then two different arrangements are possible.

Question 4

cis isomer

Answer 4

has the same groups on the same side of the C=C

Question 5

trans isomer

Answer 5

has the same groups on opposite sides of C=C

Question 6

when can cis-trans isomers occur

Answer 6

when there are two different groups or atoms attached to the C at each end of the double bond
