Help needed with question 1 of the image attached

1. Below are four organic compounds. The reagent shown is added to the compound. What should you
visually see when the two materials are mixed together? Write the structure of the product; if no
reaction, write NR.
a. CH₂-CH=CH₂ + Bra
b.
e. CHg=CH=CH-CH,
d.
+ KMnO4 (aq)
e.
+ KMnO4 (aq)
a. Water solubility
b. Ligroin solubility
c. Combustion
d. Density versus water
2. A student has two compounds in two separate bottles but with no labels on either one. One is an
unbranched alkane, octane, C3H₁8; the other is 1-hexene, an unbranched alkene, C6H12. Based on
your observations in this experiment, tell what you should see in the following tests:
1-Hexene
Octane
+ H₂SO4 (conc.) -
Bromine test
f. Permanganate test
➜
3. An unknown compound, believed to be a hydrocarbon, showed the following behavior: it burned
with a yellow sooty flame; no heat or color appeared when sulfuric acid was added; permanganate
solution remained purple; the red color of bromine solution was lost only after a catalyst was added.
From the compounds below, circle the one that fits the observations. Write equations for the tests that
work.
CH₂CH₂CH₂CH₂CH₂
H-C=C-CH₂CH₂CH₂
