Question:

Which compound would react faster when treated under acidic conditions: 1-butanol or 2-methyl-2-butanol?

Answer:

Reaction of alcohols under acidic conditions requires carbocation formation. Stability of carbocation ranges from tertiary as more stable, secondary as mid-way, and primary being less stable. 1-butanol is primary, while 2-methyl-2-butanol is tertiary. Forming the most stable carbocation would result in the faster reaction, hence 2-methyl-2-butanol would react faster.

Answer:

Squeezing a balloon would lower the volume. Based on the Gas Law, decrease in volume would result in increase in pressure. In fact, continuous increase in pressure may result in balloon bursting.
