what is the other name for ethyne i.e. CH(triple bond)CH?
105306
acetylene. usually any carbon compound with two carbons gets the 'nick name' starting with acetyl-  like u take acetic acid for example .. it's got CH3-COOH two carbons hence ACETic-acid

.........CH3\n..........|\nCH3 - C  - CH2 - CH2 - CH2 - CH3\n.........      |\n........      CH3\n\nPlease ignore the full stops in the above image (which i had to insert to get the correct spacing).\n\nI hope that this helps you.

This may not be entirely correct, but I'm fairly certain that 2, 2 dichloropentane would be a five carbon hydrocarbon. The second carbon (from left or right, it doesn't matter) would have two chlorines attached to it, rather than two hydrogens. \n\nSo, this structure would be: CH3 - CCl2 - CH2 - CH2 - CH3.

Yes, CN- has a triple bond, and N is slightly more EN than C, Remember that electronegativity increases up and to the left in the periodic table!

All alkanes exist as two or more isomers is not true\n\nbecause methane, ethane and propane are also alkane, but they have no isomers.

C2H5OH\n\nThe end (-anol) tells you it's an alcohol, which means it has an OH group somewhere.  The begining (eth-) is the prefix used in organic chemistry to mean two, which tells you there are two carbons.  The two carbons are bonded to each other (that's just how alcohols work, because of the electronegativities of the atoms), and each one can bond to three other things.  If it were an alkane (the simple ones that are just a carbon chain surrounded by the maximum possible hydrogen atoms), it would be two carbons with six hydrogens around it (which is called ethane), but since it's an alcohol, there has to be an OH group somewhere, which is added basically by sticking an oxygen between one of the carbon-hydrogen bonds in the alkane.  That leaves you with two carbon atoms, six hydrogen atoms, and one oxygen atom, giving a molecular forumla of C2H6O.  But because the OH is basically one thing, it's generally written like that is a single atom, so the molecular forumla for ethanol is given as C2H5OH.

CH3CH2C(CH3)3.\nI guess you forgot to type the C before the parenthesis. If you didn't forget, then none of the answers is correct (you would be missing a carbon atom).\n\nChem-man I would have contacted you in private about this but you do not give us the option to e-mail you. I have seen several of your answers prompting askers to verify your answer through echemistryhelp. I checked the website and it is not a free one; you post a question and pay for the answer. I'd say that this is a form of indirect advertisement  which is against the community guidelines. Please refrain from doing that or I will have to report you.

This might not make much sense, but I think it might be\n2,4-Cyclohexadiene with an ammonia substituent.

Ethanol, or ethyl alcohol.\n\nSplit the water (H2O) into H and OH.\nSplit one of the bonds of the double bond two form two new single bonds.\nAttach the H to one, the OH to the other, to form H3C-CH2OH.

The bonding will indicate both of these. \na) CH3OH - sp3 O - H single bond\nb) CO32- sp2 O-H 1/3 double bond character through resonance\nc) CO2- sp C - sp2 O, double bond\nd) CO - sp C - sp O, triple bond\nThen longest to shortest is: a) b) c) d)\nWeakest to strongest is: a) b) c) d)

When naming organic compounds, you must always look for the longest continuous chain of carbons.  The positions of the branches are numbered from the carbon that will give the lowest numbers.  Therefore the compound you mentioned would be more properly named *4-methyl-5-propylnonane*.\n\nIt can't be benzene or toluene.  Those are both ring shaped and would have the prefix "cyclo" in the name.
