Pressure of a gas is a measure of the number of hits the gas molecules have on
its container.
At the same temperature, smaller particles move more quickly that larger
particles.
The motion of particles increases as the surrounding temperature increases.

In an alkyl halide, the halogen serves 2 functions
that render the alkyl halide reactive towards
substitution and elimination processes. One is
that halgens serve as leaving groups and
substitution/elimination
reactions can only occur
when a leaving group is present. What is the other
reason?
The halogens have pką values above
zero, making them weaker acids and
more likely to participate in dissolution.
The halogen repels electron density
rendering the adjacent carbon atom
nucleophilic and therefore subject to
attack by an electrophile.
The halogen is usually in an allylic
postion and therefore does not
participate in resonance, making it less
stable and more likely to react.
The halogen withdraws electron
density rendering the adjacent carbon
atom electrophilic and therefore
subject to attack by a nucleophile.

What was the driving goal of the late nineteenth-century Can Vuong resistance
movement in what is now Vietnam?
to establish a communist republic in the region
to establish a democratic republic of ethnic Vietnamese only
to ally with the British as a means of expelling the French from the region
to bring the local king back to power and expel the French
to accept French control but extract far better terms for the local population
under French rule
