Alkanes and Alkenes

If 1-butene reacts with HCl the main product is:

• 1-chlorobutane

• 2-chlorobutane

• 1,2-dichlorobutane

• 1-chlorobutene

Cis-2-butene and Trans-2-butene:

• undergo electrophilic addition reactions

• undergo electrophilic substitution reactions

• react with HCl giving 2 different products

• are conformational isomers

The cyclohexane:

• is stable thanks to its 120 ° angles

• is stabilized by resonance

• undergoes electrophilic substitution reactions

• can assume different conformations

A molecule with the C₆H₁₂ formula reacts with Br₂ to give a compound with formula C₆H₁₂Br₂. The molecule is:

• An alkane

• A cyclohexadiene

• An Alkene

• An aromatic compound

All statements regarding the molecule CH₃-CH=CH-CH₃ are true EXCEPT one:

• the Cis- and Trans- isomers exist

• its name is 2-butene

• The hydration reaction (addition of water) yields 2 isomers of butanol

• the hydrogenation reaction produces butane
