Choose the true statement about the reaction. cis-2-pentene trans-2-pentene K = 4.3 O There are roughly the same number of trans-2-butene molecules as there are cis-2-butene molecules. O There are slightly more than four cis-2-butene molecules for each trans-2-butene molecule. O There are slightly more than four trans-2-butene molecules for each cis-2-butene molecule. O There are slightly less than four trans-2-butene molecules for each cis-2-butene molecule.

Consider the following isomers of octene:

For each molecule, draw the structure and indicate whether cis/trans isomers are possible. If they do, draw them both and label them as cis and trans. a. 2-methyl-1-butene b.1,2-dimethylcyclohexane

For the equilibrium reaction: 2 NOCI(g) → 2 NO(g) + Cl2(g) 5.00 mol NOCI was placed in an otherwise empty 1.00-L flask at a certain temperature. When the system reaches equilibrium 0.89 mol NO is present. Calculate Kat that temperature. 2.1x10-2 48 4.2x10-2 O 1.4×10-2

Which statement of the following is false? A. Cyclohexene has the general formula CH20-2 B. Alkenes are also referred to as olefins O C. The alkene C atoms are sp2 hybridized and have a bond angle of 120°C D. Trans isomers are identical to (Z) isomers E. The bond angle around the alkyne C atoms is 180°C
