<p>Which one has the higher boiling point, I2 or Radon? The book answer is iodine…
Which gas deviates more from idea gas behavior?
SO2 or Ne? Book answer is SO2…</p>
<p>SO2 is clearly correct. it’s more massive than neon (meaning it has more electrons which can create induced dipoles… meaning more forces of attraction), even if you didn’t know that you should know that neon is a noble gas, so it’s inert. which is basically what the ideal gas laws say - the gas molecules are treated basically like individuals that have little attraction for each other.</p>
<p>as for I2 and Radon, I2 does have a higher boiling point.</p>
<p>these aren’t typos, you just need to review your notes.</p>
<p>i c, but how can i distinguish which one below has higher melting point
S8 I2 SiO2 SO2 C6H6?</p>
<p>well you should recognize that SiO2 is a network covalent solid, if you know what that is i’m sure you have reached your answer.</p>
<p>I agree with stephen that the Barron’s book is correct on the questions you mentioned. I also want to point out that Barron’s does have few typos throughout the book so you might run into some later. </p>
<p>As for your 3rd post question, SiO2 is a network covalent, which means it probably have the highest melting point. At room temperature: SO2 is a gas. S8 is an amorphious (spelling?) solid. C6H6 is probably a gas or liquid.</p>
