Question

In a replacement reaction, which nonmetal would replace chlorine
A. iodine
B. astatine
C. fluorine
D. bromine

Answer 1

In a replacement reaction, a more reactive nonmetal can replace a less reactive one from a compound. Chlorine is a halogen, and its reactivity is lower than that of fluorine, but higher than that of bromine, iodine, and astatine.

Among the options given:

A. Iodine - Less reactive than chlorine.
B. Astatine - Also less reactive than chlorine and typically behaves similarly to iodine.
C. Fluorine - More reactive than chlorine.
D. Bromine - Less reactive than chlorine.

The only nonmetal that could replace chlorine in a replacement reaction is **C. fluorine**, as it is more reactive than chlorine.
