Question

question 1 of 30 what is the name of the opposite stereoisomer of the molecule shown below? a. cis-2-pentene b. trans-2-pentene c. 1-propene d. 2-ethylpropane

Explanation:

The molecule shown has a double bond with substituents on the same side (cis - 2 - pentene structure). The opposite stereoisomer (trans) of cis - 2 - pentene is trans - 2 - pentene. 1 - propene has a different carbon chain length, and 2 - ethylpropane is an alkane, not an alkene with stereoisomerism here.

Answer:

B. trans - 2 - pentene
