Question:My organic chem lab on webassign is asking what the boiling point of acetone is. I have tried 56.53, 50.5, and 53 and it has counted all of them wrong.

Answers:I looked in two organic chemistry references and both of them say acetone boils at 56.2 C. If in doubt you could try distilling some and use a thermometer to see the boiling point; if you try it remember acetone is flammable - use caution!

Question:

Answers:Acetone is the organic compound with the formula OC(CH3)2. This colorless, mobile, flammable liquid is the simplest example of the ketones. Owing to the fact that acetone is miscible with water it serves as an important solvent in its own right, typically as the solvent of choice for cleaning purposes in the laboratory. More than 3 million tonnes are produced annually, mainly as a precursor to polymers. **This has a boiling of 56.53 C, 330 K, 134 F Propan-1-ol is a primary alcohol with the molecular formula of C3H8O. It is also known as 1-propanol, 1-propyl alcohol, n-propyl alcohol, n-propanol, or simply propanol. It is an isomer of propan-2-ol. It is used as a solvent in the pharmaceutical industry, and for resins and cellulose esters. It is formed naturally in small amounts during many fermentation processes. **This has a boiling point of 97.1 C, 370 K, 207 F So, The answer to the your question is that Propanol has a higher boiling point then Acetone.

Question:

Answers:The equation for converting degrees Celcius to degrees Fahrenheit is F = 1.8C + 32 Substituting C = 56.1 gibes F = 1.8*56.1 + 32 F = 133, or 133 degrees Fahrenheit.

Question:Acetone (CH3)2CO is a substance widely used as an industrial solvent. (a) Draw the Lewis structure for the acetone molecule, and predict the geometry around each carbon carbon atom. (b) Is the acetone molecular polar or nonpolar? How can you tell? (c) What kinds of intermolecular atrractive forces exist between acetone molecules? (d) 1-Propanol, CH3CH2CH2OH has a molecular weight that is very similarto that of acetone, yet acetone boils at 56.5 C and 1-propanol boils at 97.2 C. Explain the difference. For (a) is there a chain of three C and 3 H on the first and third C and a double bond to O on the middle C??? is the molecular geometry tetrahedral, trigonal planar, tetrahedral? For (b) is it nonpolar?...but i don't know why For (c) is it dipole dipole forces...how can you tell I have no idea how to do (d)

Answers:For ace toneThe first and third C are Sp3 so its tetrahedral the C on the second is a Sp2 so its trigonal planer b) Hmm bit of a trick quesiton actone has a slight polar movement from the second carbon to the oxgyen atom. But if you have a mirror down the middle of the C=O bond the dipole on the first and third carbons are the same and hence there is no dipole movement in this direction. c) Long time since I did this, the oxygen on actone will have a slight atttraction to another second carbon on another actone compound due to dipole dipole forces. d) 1-propanol has less simarilty and the hydroxy group can undergo hydrogen bonding with other 1-propanol groups this causes an increase in the boiling pt when compaired to acetone. Plus with the hydroxy group being at one end of the compound the dipole movement is much greater than that of acetone as. Th
