2015年12月18日 · Took a while... I found 28 optical isomers, but 19 constitutional isomers (seeing as how each R/S optical isomer, or each cis/trans geometric isomer, have the same connectivity). You do not have to know all of these. This is just an exercise to get you thinking.

2015年11月23日 · I count four constitutional isomers of "C"_4"H"_9"Br". > First draw all the constitutional isomers of "C"_4"H"_10. You get (from hardinars.tk) and Then put a "Br" atom in every possible location on each of the carbon skeletons. From the straight-chain isomer, we get 1-Bromobutane and 2-Bromobutane From the branched-chain isomer, we get 1-Bromo-2 …

2016年3月5日 · 3 isomers C_3H_8O has three constitutional isomers: 1-propanol: CH_3-CH_2-CH_2-OH 2-propanol: CH_3-CH(OH)-CH_3 ethyl-methyl ether: CH_3-CH_2-O-CH_3 There are no geometric isomers or stereoisomers posssible for these structures

2016年1月1日 · There are four possible constitutional isomers of "C"_4"H"_9"Cl". > First draw all the constitutional isomers of "C"_4"H"_10. You get (from hardinars.tk) and Then put a "Cl" atom in every possible location on each of the carbon skeletons. From the straight-chain alkane, we get 1-Chlorobutane and 2-Chlorobutane From the branched-chain alkane, we get 1-Chloro-2 …

2016年2月25日 · 2-methyl-pentane, 3-methyl-pentane, 2,2-dimethyl-butane, 2,3-dimethyl-butane Isomers have same molecular formula (in this case C_6H_14), but different structural formulae. Hence the hydrocarbon alkane structural isomers are as shown in the sketch below:

2015年11月23日 · I count 11 isomers of "C"_3"H"_6"O". > They are: Prop-2-en-1-ol (from commons.wikimedia.org) Methoxyethene Propanone (from www.meritnation.com) And its tautomer, Prop-1-en-2-ol Propanal (from commons.wikimedia.org) And its two tautomeric isomers (Z)-Prop-1-en-1-ol and (E)-Prop-1-en-1-ol Then we have Cyclopropanol Oxetane (R) …

2015年11月23日 · I count six isomers of "C"_4"H"_8. > An alkane with 4 carbon atoms would have the formula "C"_4"H"_10. This hydrocarbon has two hydrogens less, so it must contain either a double bond or a ring. The six possibilities are: But-1-ene cis-But-2-ene (from commons.wikimedia.org) trans-But-2-ene 2-Methylpropene Cyclobutane Methylcyclopropane …

2015年11月24日 · There are four isomers of "C"_3"H"_9"N". > They are propylamine Isopropylamine. A third amine is N-methylethylamine. And the fourth amine is trimethylamine.

2015年11月11日 · See below. > We know from the formula that these isomers contain no rings or double bonds. The isomers must be alcohols and ethers. Let's start by drawing the alcohols. Start with four carbons in a row and put an "OH" group in every possible position. This gives us 1. "CH"_3"CH"_2"CH"_2"CH"_2"OH", butan 1-ol and 2.

2016年3月6日 · Structural Isomers are 2. The first one is 1,2-dichlororethane; And. The second one is 1,1-dichlororethane.
