What is pentene?
An alkene
Which molecule is a stereoisomer of cis-2-pentene?
Trans-2 pentene is a stereoisomer of cis-2-pentene.
Why 3-pentene incorrect?
You take the lowest number carbon from the outside of the molecule to determine the prefix, whether this be the left hand side or the right hand side. e.g. C-C-C=C-C is the same isomer as: C-C=C-C-C Both are 2-pentene. The double bond on the third carbon will always be between a carbon that is closer to the end of the molecule (therefore lower in number), so it is this carbon that will dictate the prefix. Therefore the only 2 isomers of Pentene are 1-pentene and 2-pentene.
Which molecule is an alkene?
cis-2-pentene
Why is 1-pentene less stable than 2-pentene?
Because the "reactive" double-bond is at the "exposed" end of the carbon-chain molecule rather than at the more internal position found in either of the two isomers (cis & trans) of 2-pentene.

Five carbon atom with one double bond?
A molecule with five carbon atoms and one double bond is pentene. Pentene can exist in different isomeric forms, such as 1-pentene and 2-pentene, depending on the position of the double bond along the carbon chain. The general formula for pentene is C5H10.
Which molecule is a stereoisomer of trans-2-pentene?
You think probable to cis-2-pentene.
How many hydrogen atoms would be needed in an addition reaction to convert one molecule of 2-pentene to one molecule pentane?
The molecular formula of 2-pentene is C5H10 and the molecular formula of pentane is C5H12. Therefore, (12 - 10) or 2 hydrogen atoms per molecule will be needed to convert pentene to pentane.
Which molecule is a branched alkane A. Nonane B. trans-2-pentene C. 2-nonyne D. 3-methylhexane?
cis-2-pentene
What type of molecule is 2-methylpentene?

What is pentene?
An alkene
Which molecule is a stereoisomer of cis-2-pentene?
Trans-2 pentene is a stereoisomer of cis-2-pentene.
What is the equation for addition of bromine to pentene?
The addition of bromine to pentene typically follows the general equation: C5H10 + Br2 --> C5H10Br2. This reaction is an example of electrophilic addition where the bromine molecule is added across the carbon-carbon double bond in pentene.
Why 3-pentene incorrect?
You take the lowest number carbon from the outside of the molecule to determine the prefix, whether this be the left hand side or the right hand side. e.g. C-C-C=C-C is the same isomer as: C-C=C-C-C Both are 2-pentene. The double bond on the third carbon will always be between a carbon that is closer to the end of the molecule (therefore lower in number), so it is this carbon that will dictate the prefix. Therefore the only 2 isomers of Pentene are 1-pentene and 2-pentene.
What is the difference of trans-2-Pentene and cis-2-Pentene?
The main difference between trans-2-pentene and cis-2-pentene lies in the arrangement of the substituents around the double bond. In cis-2-pentene, the two methyl groups (CH₃) are on the same side of the double bond, resulting in a more polar molecule. Conversely, in trans-2-pentene, the methyl groups are on opposite sides, leading to a more symmetrical, less polar structure. This difference in geometry affects their physical properties, such as boiling points and solubility.
