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.
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.
The following description applies to more than one alkane: (4-ethyl-2-methylhexyl)cycloalkane. Draw at least two structures that match this description and provide the systematic name for each structure drawn.
Given the incorrect name below, rename it using IUPAC nomenclature. [Use the incorrect name given, draw the structure first, and then assign it a proper name.]
3,4-diethyl-5-methylcyclohexane
Write the structural formula and determine the molecular formula for (i): 1-ethyl-3-methylcyclohexane and (ii): isobutylcyclopentane.
Draw the appropriate structure for each name.
(i): 2,3,4,5-tetramethylhexane
(ii): trans-1,3-dimethylcyclohexane
What is the systematic name of each compound?
A 1° carbon is attached to one carbon, a 2° to two carbons, a 3° to three carbons, and a 4° to four carbons. Classify each of the carbons in 1-(tert-butyl)-3-ethylcyclopentane.
Draw all the isomers of a cyclopentane ring with a molecular formula C 7H14.
