What is the condensed formula of pentene?
The compound CH3CH=CHCH2CH3, for example, has the double bond between the second and third carbon atoms. Its name is 2-pentene (not 3-pentene)….13.1: Alkenes- Structures and Names.

Does pentene exhibit geometrical isomerism?
1-Butene consists of a chain of four carbons, having a double bond between carbons 1 and 2. Because carbon 1 has two of the same substituent (in this case, H), 1-butene does not exhibit geometric isomerism, unlike its structural isomer, 2-butene (see below).

What type of isomerism is exhibited by pentene 2?
From the structures, we can see that 2-pentene has different atoms or groups of atoms attached on each side of the double bond. Thus, 2-pentene will exhibit cis-isomer and trans-isomer.
What is the structure of 2-pentene?
What is the condensed structural formula for cis-2-butene?
CH3CHCHCH3
cis-2-Butene | CH3CHCHCH3 – PubChem.
What does the number 2 in the name 2-pentene have to do with the structure of 2-pentene?
The longest chain containing the double bond has five carbon atoms, so the compound is a pentene (rule 1). To give the first carbon atom of the double bond the lowest number (rule 2), we number from the left, so the compound is a 2-pentene.
