Question

question 5 (1 point)
a structural diagram for 2 - butene shows the ch₃ groups on the same side of the carbon atom. this compound is __________.
○ a) cis - 2 - butene
○ b) trans - 2 - butene
○ c) 2 - butanol
○ d) di - methylbutene
○ e) none of the above

Explanation:

In organic chemistry, for alkenes like 2 - butene, when the two same groups (here \(CH_3\) groups) are on the same side of the double - bonded carbon atoms, it is called the cis isomer. The trans isomer has the same groups on opposite sides. 2 - butanol is an alcohol (has an - OH group), and di - methylbutene has two methyl groups attached to a butene chain (different structure from the description).

Answer:

A. cis - 2 - butene
