the lack of rotation of the double bond
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.
all the non terminal straight chain alkenes show the geometrical isomerism..
The molecule CH3-HC=CH-Br can exist either in the cis or trans configuration.
The geometrical isomerism is mainly Cis-trans isomerism but in some cases we use another term Z and E isomers, they are almost same.
No. When bromine (aq) reacts with cyclohexene, the compound is now saturated, and will no longer have C=C bonds, thus it is unable to exhibit cis-trans isomerism.
Geometric isomerism also known as cis-trans isomerism or E-Z isomerism

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)

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
Restricted rotation of the carbon-carbon double bond.
The molecule CH3-HC=CH-Br can exist either in the cis or trans configuration.
those are defined by position of double bonds, the possible one,s are cis-cis,cis-trans,trans-trans.
