Tartaric acid has three stereoisomers that are drawn below T

Tartaric acid has three stereoisomers that are drawn below. The properties of the first isomer are listed. If you can, assign the physical properties for the other two based on the first isomer or other information. If you cannot explain why. 8 pts 7. HO COOH H COOH OH HOOCH HOOC O HOOC O [a]20 = +12.0 MP: 168-170 °C d = 1.76 g/mL

Solution

The second structure is the same as of the first structure so are the properties.

The third one is different from the first two as the OH group is on the opposite sides of the plane of the structure. So the properties of the structure will also vary from the first one. The second one will have negative polarity (alpha = -12)

The melting point will increase because of its structure which does not have that much hindrance as in the first two and higher extent of inter and intra molecular hydrogen bonding. But the density will nearly be the same as the mass and the overall volume will not be effected.
