Chemical Bonding And Molecular Structure Question 243
Question: Among the compounds, $ BF_3,NCl_3,H_2S,SF_4 $ and $ BeCl_2 $ , identify the ones in which the central atom has the same type of hybridisation [Kerala PMT 2004]
Options:
A) $ BF_3 $ and $ NCl_3 $
B) $ H_2S $ and $ BeCl_2 $
C) $ BF_3,NCl_3 $ and $ H_2S $
D) $ SF_4 $ and $ BeCl_2 $
E) $ NCl_3 $ and $ H_2S $
Show Answer
Answer:
Correct Answer: E
Solution:
In $ NCl_3 $ and $ H_2S $ the central atom of both (N and S) are in $ sp^{3} $ hybridization state while in $ BF_3 $ and $ NCl_3 $ central atoms are in $ sp^{2} $ and $ sp^{3} $ hybridization respectively. In $ H_2S $ and $ BeCl_2 $ central atom are in $ sp^{3} $ and $ sp^{2} $ hybridization In $ BF_3,,NCl_3 $ & $ H_2S $ central atom are in $ sp^{2} $ , $ sp^{3} $ & $ sp^{3} $ hybridization and in the central atom are in $ sp^{3} $ and $ sp $ hybridization.
