Answer:
What that means is that when pressure and number of moles are kept constant, increasing the temperature will result in an increase in volume. Likewise, a decrease in temperature will result in a decrease in volume. In your case, the volume of the gas decreased by a factor of about 3, from "140.0 mL" to "50.0 mL".
According to Newton's first law of motion, it takes an unbalanced force to move an object at rest.
I hope this helps :)
The given Benzene derivative contains an
ethyl group and a
<em>tertiary</em> butyl group. As we know when
Alkylbenzene is treated with
KMnO₄ it results in the oxidation of alkyl group and forms
Benzoic Acid.
In our case benzene has two alkyl groups. The carbon next to benzene carbon is called
benzylic carbon. If this position has any H atom then it will be oxidized, otherwise the groups like <em>
tert.</em>
Butyl having no benzylic hydrogen are not oxidized.
The reaction is as below,
