is 2-pentene a cis or trans? and why?
Cis- atleast 2 bulky grps..
Trans-3-4 bulky grps..
cis and trans must contain a double bond. i don't know if its a cis or trans so please enlighten me
please
I don't understand the problem. There is a cis-2-pentene and a trans-2 pentene. If the H atoms are on the same side it is cis and if they are on the opposite sides trans. Read about it here.

To determine if 2-pentene is cis or trans, you need to look at the arrangement of the atoms around the double bond. Cis and trans isomerism refers to the relative positions of substituents on opposite sides of a double bond.
In the case of 2-pentene, it is important to identify the substituents on each carbon of the double bond. Pentene is a five-carbon molecule with a double bond between the second and third carbons. The remaining carbon atoms would be numbered consecutively, with the double bond being between carbon 2 and carbon 3.
Now, let's determine if there are any bulky groups on each side of the double bond in 2-pentene. If there are, it is possible for the compound to exist in the cis form. However, if there are no bulky groups or only one bulky group, then it would exist in the trans form.
Since 2-pentene does not have any substituents mentioned in the question, we cannot definitively determine if it is cis or trans. To know for sure, you would need to provide additional information about any substituents attached to the carbon atoms adjacent to the double bond.
