2. A molecule has a MF = C4H6O (SoapBar = 2). Its IR spectrum shows sharp, strong absorbance at 3300 cm-, a weak, sharp absorbance at 2200 cm and NO other absorbances above 3000 cm. Draw a Lewis structure (showing all atoms and lone pairs) consistent with these data. No formal charge!

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.

it's 3.2 on edge, i just took the test.
