Question

When chlorine water is exposed to sunlight, $O_2$ is liberated. Hence,

• A. hydrogen has little affinity to $O_2$
• B. hydrogen has more affinity to $O_2$
• C. hydrogen has more affinity to chlorine
• D. it is a reducing agent

Answer 1

Answer: (C)

hydrogen has more affinity to chlorine

Answer 2

When chlorine water is exposed to sunlight, $O _{2}$ is liberated. Hence hydrogen has more affinity to $Cl _{2}$
$2 Cl _{2}+2 H _{2} O \xrightarrow{\text { sunlight }} O _{2}+4 HCl$
Thus, chlorine can displace oxygen from water. This indicates that the affinity of hydrogen for chlorine is more than the affinity of hydrogen for oxygen.
