What is a methyl ketone? + Example - Socratic
2015年12月23日 · A ketone is an organic compound containing a carbonyl group (C=O) bonded to two hydrocarbon groups. In a methyl ketone, at least one of the hydrocarbon groups is a methyl group. (from newscenter.lbl.gov) Some examples of methyl ketones are acetone, CH3COCH3, ethyl methyl ketone. (CH3CH2COCH3), and acetophenone (C6H5COCH3).
Would cyclohexanone be a methyl ketone? - Socratic
2015年11月13日 · A methyl ketone and a cyclohexanone structure look like this:. One could argue that cyclohexanone doesn't count as a methyl ketone since a methyl ketone requires a methyl group on one side and an #"R"# group on the other, but a methylene (#\mathbf(-"CH"_2-)#) is not the same as a methyl (#\mathbf(-"CH"_3)#) since a …
Question #c2038 - Socratic
2016年3月31日 · In order to find methyl ethyl ketone's (MEK) percent composition, you need to pick a sample of this compound and try to figure out how many grams of carbon, #"C"#, hydrogen, #"H"#, and oxygen, #"O"#, it contains. Notice that one mole of MEK contains . four moles of carbon, #4 xx "C"# eight moles of hydrogen, #8 xx "H"# one mole of oxygen, #1 xx ...
What are the 7 ketones with formula C6H12O? - Socratic
2015年11月18日 · 1 Answer. Making use of symmetry, and the fact that it must be a ketone, the carbonyl group can only move between carbons 2 and 3. That makes for the first two isomers. Two more isomers involve shifting the terminal methyl group up one to carbon 4. The fifth and sixth isomers are enantiomers, the top of which is R and the bottom of which is S.
How would you convert an aldehyde to a ketone? | Socratic
2015年11月16日 · What's special about it is that it oxidizes alcohols one step forward, i.e. primary alcohol to aldehyde, or secondary alcohol to ketone. If you think about it, all you do is add a carbon, so what you need is a nucleophile that can attack at the carbonyl carbon that looks like an \mathbf"R" group. A straightforward solution is "R"-"MgBr", an ...
Why are aldehydes more reactive than ketones? | Socratic
2016年5月28日 · Consider the shrubbery around the carbonyl group in an aldehyde, versus that around a ketone group. Should we compare RC(=O)H to RC(=O)R, clearly the aldehyde is less sterically encumbered. Even for acetone versus acetaldehyde, the ipso carbon is encumbered by 2 methyl groups in the ketone, versus 1 methyl in the aldehyde. So in terms of sterics, the aldehyde should be a much more reactive ...
Ozonolysis - Organic Chemistry - Socratic
What is an ozonide in the mechanism for ozonoide formation? An ozonide is the 1,2,4-trioxolane structure that is formed when ozone reacts with an alkene, The first intermediate in the reaction is called a molozonide. A molozonide is a 1,2,3-trioxolane (tri ="three"; oxa = "oxygen"; olane = "saturated 5-membered ring"). The molozonide is unstable.
What aldehydes and ketones are water soluble? | Socratic
2016年2月21日 · The general rule of thumb is that aldehydes and ketones with fewer than six carbon atoms are water soluble. > The solubility of an aldehyde or ketone is a competition between its polar "head" and its nonpolar "tail". Small aldehydes and ketones are miscible with water in all proportions, because they can form hydrogen bonds with water. However, solubility decreases with chain length, because ...
Introduction to IUPAC Nomenclature - Organic Chemistry - Socratic
For example, either isobutylmethyl or methyl isobutyl are fine. sec-and tert-are not alphabetically significant unless compared with each other. For example, you can say isobutylmethyl ketone, OR methyl isobutyl ketone. An example of a normal case would be 1-ethyl-2-methylpropane, where methyl comes after ethyl.
A ketone has the molecular formula C5H10O. Write the ... - Socratic
2015年7月27日 · A ketone has one double bonded oxygen atom, but not at the end of a (sub) chain (or it would be an aldehyde). Step 1: Make a straight chain of C's. You can place the =O at the second or third C (number 1 and 5 are not allowed, and 4 would be the same as two). Of course, you fill the rest of the valencies with H atoms. Step 2: Make a chain of 4 C's and put a branch-C at number 3. Number 3 has ...
