Neet Solved Paper 2013 Question 13
Question: Dipole-induced dipole interactions are present in which of the following pairs?
Options:
A) $ {H_2}O $ and alcohol
B) $ C{l_2} $ and $ CC{l_4} $
C) $ HCl $ and He atoms
D) $ Si{F_4} $ and He atoms
Show Answer
Answer:
Correct Answer: C
Solution:
- Dipole-induced dipole interaction are present in the pair in which the first species is polar and the other is non-polar. $ {H_2}O $ and alcohol both are polar molecules, so there exists dipole-dipole interactions in between them. $ C{l_2} $ and $ CC{l_4} $ both are non-polar so there exists induced dipole-induced dipole interactions in between them. Similar is true For $ SiC{l_4} $ and He atoms pair. HCI is a polar molecule, whereas He atoms are non-polar, so in between them dipole-induced dipole interactions exist:
