What Is The Name Of The Compound H3C-O-CH3? - ECHEMI

What is the name of this ester compound? CH3-CH=CH-CH2-OC=O-CH2-CH2-CH3?

The line notation is a little messed up. The fragment C=O-O implies that the carbon is double-bonded to an oxygen which is then single-bonded to another oxygen. The middle oxygen has three bonds, which can’t happen unless it also bears a formal positive charge, as in H[math]_3[/math]O[math]^+[/math]. The proper line formula would be CH3-CH=CH-CH2-OC(=O)CH2-CH2-CH3, where the parentheses around the (=O) imply that it is not part of the main chain. An equally (or even more) proper line formula would omit all the single bonds, as in CH3CH=CHCH2OC(=O)CH2CH2CH3.

Once that’s fixed, it’s pretty easy to convert the line formula into a structural drawing:

The common name of H3C-O-CH3 is dimethyl ether and it is the simplest ether in organic chemistry.

Its IUPAC name is methoxy methane.

It is an isomer of ethanol (ethyl alcohol, C2H5OH) as both have the same molecular formula, C2H6O.

The condensed structural formula of the compound is shown below.

The molecular formula CH3O may refer to:

• hydroxymethyl (HOCH2–)
• Methoxy group (H3CO–)

They are two ways of writing a methyl group. If a CH3 group is being drawn on the left-hand side of a benzene ring using H3C- shown the correct bonding sequence. i.e. Toluene is C6H5-CH3 or H3C-C6H5. But we all understand what CH3-C6H5 means as well. Artistic license.

Such structure has no existance. It’s actually CH3-CH2-CH3 and its name is propane.

The question originally was (since I don’t trust how Quora changes questions so the answer makes no sense): Is the sequence CH3-Che-CH3-H3C?

I’ve been a chemist or student of chemistry for over sixty years, and I have no idea what “Che” is. Whatever it is, there is no way that the group to the right of it could exist, as it has a carbon atom with 5 covalent bonds.

2–chloro–5,5–dimehylhexanal

According to IUPAC nomenclature, the prefix for two carbon atoms in a compound is “Eth".

As the compound contains two carbon atoms it's IUPAC name will be “Ethane” with “ane” as suffix as it contains single bond between two carbon atoms.

First we need to identify the parent chain which contains the maximum number of carbon atoms in it. So in this case we have 4 carbon atoms in the parent chain and one methyl group outside the parent chain. In this compound the functional group is alcohol (- ol) so starting the numbering from the carbon directly attached to the -OH group, we have methyl group attached to the second carbon atom. Therefore according to the rules of IUPAC Nomenclature first mention the substituent and its position followed by primary and secondary suffixes. Thus, IUPAC name of the compound will be 2-methylbutan-1-ol or simply 2-methyl-1-butanol.

This is called “ But-2-yne”.
