Can someone complete this reaction: propane + chlorine gas -->

is this right:
propane + chlorine gas --> 2-chloropropae + 1-chloropropane + HCl

would this be only an addition reaction,
only a substition reaction,
or both an addition and substitution reaction.

oh and if you can,
in the elimination reaction of butane with the catalyst H2SO4 are the products 1-butene, 2-butene and hydrogen gas?

butane ----> 1-butene + 2-butene + hydrogen gas
thanks!

Your first reaction (propane) is correct, although you need to include hv on top. The reaction proceeds by a radical mechanism and requires light as a catalyst.

The reaction is neither addition nor substitution. The mechanism is radical-based, so there are 3 steps: initiation, propogation, and termination.

There is no elimination reaction between butane and H2SO4. Perhaps you mean butanol?

Its called free radical substitution reaction.

Your equation is wrong. its kind of hard to type it out. so i'll give you a link

for your second equation. i believe its wrong. i think your thinking of cracking. but no point in cracking butane.
