1,2-Diethylcyclobutane is more stable with a trans geometry while 1-3-diethylcyclobutane is more stable with a cis geometry. Figure out the reason behind this by drawing their structures.
Identify the name for the cycloalkane below according to the IUPAC nomenclature system.
Each of the descriptions given below applies to more than one cycloalkane. Draw two structures for each of the given descriptions and provide a name for each.a. trans-dimethylcyclobutaneb. cis-dibromocyclopentane
Mark the hydrogen atoms as primary (1°), secondary (2°), or tertiary (3°) in the following structures.
a. Cyclobutane
b. 2,3-Dimethylbutane
Draw all the disubstituted cycloalkanes possible for the formula C7H14. Also, show the structures of cis and trans isomers where possible.
Determine the name for the given cycloalkane according to the IUPAC nomenclature system.
Draw the chair conformation of 1,2,3,4,5,6-hexabromocyclohexane with all the bromines in axial positions.
Write the name for the given cycloalkane as per the IUPAC nomenclature system.
Write the IUPAC names of the given cycloalkanes.
Determine the name for the given cycloalkane. Use the IUPAC nomenclature system.
Draw and name all the isomeric cyclobutanes consistent with the formula C6H12. Show geometric (cis-trans) isomers where possible.
The name 2-isopropyl-1-methyl-7-propylcyclooctane is incorrect. Provide its correct name according to IUPAC rules. Hint: Draw the structure that corresponds to the incorrect name first, and then correct it.
Provide a skeletal structure for each alkane with the following descriptions:
i. has nine carbons with two tert-butyl groups.
ii. composed of five carbons, and all are secondary.
iii. has eleven carbons and contains only primary hydrogens.
