Want this question answered?
1 butene doesn't have cis and trans isomers where Cis/Trans Isomerism occurs when there are two different groups on each side of the C=C bond. 1 butene doesn't have this.
the lack of rotation of the double bond
all the non terminal straight chain alkenes show the geometrical isomerism..
The cis-trans isomerism tend to be very stable. Typically, trans isomers are more stable however, an exception lies in cis-trans isomers which makes them more stable than trans isomers.
This is a single bonded compound and cis-trans isomerism is only possible when fre rotation about a bond is restricted or a double bond or cycle is essential for existence of cis-trans isomers.
The geometrical isomerism is mainly Cis-trans isomerism but in some cases we use another term Z and E isomers, they are almost same.
Geometric isomerism also known as cis-trans isomerism or E-Z isomerism

Restricted rotation of the carbon-carbon double bond.

cis/trans isomerism (also known as geometric isomerism) is a form of stereo isomerism describing the relative orientation of functional groups within a molecule. The terms cis and trans are from Latin, in which cis means "on the same side" and trans means "on the other side" or "across". Usually, for acyclic systems trans isomers are more stable than cis isomers. This is typically due to the increased unfavorable steric interaction of the substituents in the cis isomer. Therefore, trans isomers have a less exothermic heat of combustion, indicating higher thermochemical stability.trans-1,2-dichlorocyclohexanecis-1,2-dichlorocyclohexane

no for cis trans isomerism to exist, 2 conditions must be fufilled. firstly, there must be restricted rotation about the double bond. Secondly, there must be 2 different substituent groups attached to each carbon atom. In 1-pentene, one of the carbon has 2 hydrogen attached to it, thus it does not fufill the second condition. Hence, 1-pentene does not exhibit geometrical isomerism(cis-trans)
Isomerism is the phenomenon in which two or more compounds have same molecular formula but their structural formula is different. The compounds are called Isomers.There are 2 types of isomerism.1) Structural Isomerism which is further classied into 5 more types of isomerisms:i) Chain Isomerism which is due to difference in nature or the carbon chain e.g. isopentane, neopentane or n-pentaneii) Position isomerism which is due to the difference in position of the functional group or unsaturated linkage in the same carbon chain. e.g. 1-Chloropropane is the isomer or 2-chloropropane or another example is 1-butene which is isomer of 2-buteneiii) Functional group isomerism in which there are different functional group but same molecular formula. e.g. dimethyl ether is functional group isomer of ethyl alcoholiv) Metamerism is due to the unequal distribution of carbon atoms on either side of the functional group and such compounds belong to same homologous series. e.g. diethyl ether and methyl n-propyl ether are metamers.dietheyl ether: CH3 - CH2 - O - CH2 - CH3methyl n-propyl: CH3 - O - CH2 - CH2 - CH3v) Tautomerism due to shifting of proton from one atom to other in the same molecule.The 2nd type of isomerism is Cis-trans Isomerism or geometric isomerism and compounds who possess same structural formula but differ with respect to the positions of the identical groups in space are called cis-trans isomers and the phenomenon is cis-trans or geometric isomerism.
Nt sure I agree with the question. Consider the octahedral polyatomic ion Co(NH3)4Cl2+ this has trans and cis isomers (chlorines opposite each other at 180 0 or next to each other at 90 0). Generelly isomerism is rare in electrovalent compounds. One interesting example is the optical isomerism of ammonium sodium tartrate discovered by Pasteur.
