Yes, it does.
Yes
For Geometrical isomerism the free rotation about the bonds should be restricted so a double bonded or cyclic compound may show the geometrical isomerism.
Restricted rotation of the carbon-carbon double bond.
Functional group isomerism, as 1,2-butadiene and cyclobutene are its isomer, 1-butyne is its positional isomer.
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)

the lack of rotation of the double bond
2-butene show geomatric isomerism because each double bond carbon atom has two different group
Restricted rotation of the carbon-carbon double bond.
Geometric isomerism also known as cis-trans isomerism or E-Z isomerism
Tautomeric isomerism shows the shifting of a proton. This occurs when a compound can rapidly interconvert between two forms by moving a proton. For example, the keto-enol tautomeric isomerism of cyclohexane-1,3-dione, which can exist as both a keto form and an enol form by interchanging the positions of the hydrogen atom and the double bond.
The geometrical isomerism is mainly Cis-trans isomerism but in some cases we use another term Z and E isomers, they are almost same.
Its when two monosaccharide molecules can chemically join to form a double helix therefore forming a molecular bond which is consider a isomerism.
