Does cos have a dipole moment? choose the answer that best explains the reason for your choice.
1 answer:
Answer:
<span>COS has a dipole moment because it is asymmetric and the dipole moments do not completely cancel.
Explanation:
As we know in case of CO</span>₂ the net dipole moment is zero because the molecule is symmetrical and is Linear in shape. Hence, the two dipoles cancel each other.
While in case of COS, the molecule is still Linear but is Asymmetric. The Oxygen atom being more Electronegative attract the electron more from Carbon atom as compared to S, Hence making giving a Dipole Moment of 0.65 D.

Answer:
Explanation: The strengths of the inter molecular forces varies as follows -
The normal boiling point of CSe2 is 125°C and that of CS2 is 116°C, which explains the trend that as we move down the group, the boiling point of e compound increases as the size increases.
This usually happens because larger and heavier atoms have a tendency to exhibit greater inter molecular strengths due to the increase in size . As the size increases, the valence shell electrons move far away from the nucleus, thus has a greater tendency to attract the temporary dipoles.
And larger the inter molecular forces, more tightly the electrons will be held to each other and thus more thermal energy would be required to break the bonds between them.
