Q. The compound that will react most readily with gaseous bromine has the formula?
A) $C_3H_6$
B) $C_2H_2$
C) $C_4H_{10}$
D) $C_2H_4$
Explanation
[Solution] Per the official key, $C_3H_6$ (propene) reacts most readily, since allylic substitution occurs easily in the gas phase and its methyl group increases electron density on the double bond. Answer (1).
