and Examples of comparing the physical and chemical properties of alkene E/Z isomers

The 5 non-cyclic alkene and cycloalkane structural isomers of molecular formula C4H8 (Mr = 56)

Three non-cyclic alkene and two cycloalkane structural isomers, but-2-ene can also exist as E/Z isomers (an example of stereoisomerism).

There are carbon chain isomers and positional isomers of the C=C double bond.

There are functional group isomers of alkene/cycloalkane and E/Z isomers (cis/trans stereoisomers)

(1) but-1-ene (1-butene),  CH3CH2CH=CH2,  isomers of C4H8 butene alkenes structure and naming (c) doc b , alkene cannot exhibit E/Z isomerism

(2) structural formula of but-2-ene (2-butene) E/Z cis/trans isomers of C4H8 structural formula structure and naming (c) doc b , but E/Z isomers exist for this molecule

Z-but-2-ene E/Z cis/trans isomers of C4H8 structural formula structure and naming (c) doc b or E/Z cis/trans isomers of C4H8 structural formula structure and naming (c) doc b is Z-but-2-ene, (cis-2-butene, cis-but-2-ene) and  E/Z cis/trans isomers of C4H8 structural formula structure and naming (c) doc b or E/Z cis/trans isomers of C4H8 structural formula structure and naming (c) doc b is E-but-2-ene, (trans-2-butene, trans-but-2-ene), a case of stereoisomerism.

(3) methylpropene or 2-methylpropene, but 2- is not really needed here,  E/Z cis/trans isomers of C4H8 structural formula structure and naming (c) doc b, E/Z cis/trans isomers of C4H8 structural formula structure and naming (c) doc b

and the skeletal formula is skeletal formula of methylpropene 2-methylpropene advanced organic chemistry and methylpropene cannot exhibit E/Z isomerism

(4) cyclobutane , structural formula cyclobutane, C4H8 alkanes molecular structure naming (c) doc b, cyclobutane, C4H8 skeletal formula alkanes molecular structure naming (c) doc b

(5) methylcyclopropane,  structural formula methylcyclopropane alkanes molecular structure naming (c) doc b, methylcyclopropane skeletal formula alkanes molecular structure naming (c) doc b
