Chemical Bonding And Molecular Structure Question 232
Question: The percentage s-character of the hybrid orbitals in methane, ethene and ethyne are respectively [KCET 2003]
Options:
A) 25, 33, 50
B) 25, 50, 75
C) 50, 75, 100
D) 10, 20, 40
Show Answer
Answer:
Correct Answer: A
Solution:
% of s-character in $ \underset{(sp^{3})}{\mathop{CH_4}},=\frac{100}{4}=25 $ , $ \underset{(sp^{2})}{\mathop{C_2H_4}},=\frac{100}{3}=33 $ , $ \underset{(sp)}{\mathop{C_2H_2}},=\frac{100}{2}=50 $
