[DPMT 1990]
Options:
A) $ H_2O $
B) $ H_2S $
C) $ H_2Se $
D) $ H_2Te $
Show Answer
Answer:
Correct Answer: D
Solution:
$ H_2O $ $ H_2S $ $ CCl_4+I_2\to $ $ H_2Te $ $ {{104.5}^{o}} $ $ 2NaI+Cl_2\to 2KCl+I_2 $ $ 91^{o} $ $ 90^{o} $ As we go down the group electronegativity decreases due to which repulsion between bonded pairs of electron also decreases. Hence, bond angle decreases.
