Structural isomers are compounds that have?

Question

Structural isomers are compounds that have

a.the same molar masses, but different elemental composition.
b.two or more double bonds.
c.the same elemental composition, but the atoms are linked in different ways.
d.have identical structures, but contain different isotopes of the same elements.
e.the same elemental composition, but different molar masses

Answer 1

c.the same elemental composition, but the atoms are linked in different ways.

Answer 2

Structural isomers have the same atoms, but the bond sequence is different - butane vs. isobutane, for instance. In geometric isomers, also called stereoisomers, the bond structure is the same, but the relative position of the atoms in space is different. If the two isomers are mirror-images of each other, they are enantiomers; if not, they are diastereomers. L- and D-lactic acid are enantiomers of each other (they're both lactic acid because the bonds are the same; they're mirror images, so one rotates light to the right, the other to the left).

Answer 3

yep it's C. the structure of the compound is different, you can get forms Cis-isomerism and Trans-isomerism, hope it helps i just had a chemistry exam today an its kinda stuck in my head.
