A). The weaker the IMF the lower the evaporation rates of each liquid. So Pentane had the weakest IMF and Butanol has the strongest.
b).They all evaporate at different rates because of their differences in their bonds. Not all liquids are the same and they will all most likely evaporate at different times
It is clean and is blue when you take away air hope i helped.
>there is restricted rotation around the carbon-carbon double bond. (TRUE)
>the stability of the carbon-carbon double bond increases as the
number of substituent groups increases. (TRUE)
>whenever the two groups on each end of a carbon-carbon double bond
are the same, two diastereomers are possible. (TRUE)
>trans alkenes are generally more stable than cis alkenes. (NOT TRUE)
Answer: It increases the entropy
Explanation:
Entropy is the measure of degree of randomness or disorder.
Activation energy is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.
A catalyst is a substance which increases the rate of a reaction by taking the reaction through a different path which involves lower activation energy and thus more molecules can cross the energy barrier and more molecules convert to products. Thus leading to more randomness and more entropy.
Carboxylic acids: considered as weak acids due to they ionize in solution to give -COO⁻ and H⁺, they are abundant in nature, they can form intermolecular hydrogen bonds so they exist as dimers (remember that alcohols also can form hydrogen bonds).
- Acids have higher boiling and melting points than corresponding molar mass compounds due to the formation of hydrogen bond
- Aromatic carboxylic acids are solids in nature at room temperature
