    wasnt cracking equation c because i remember A had no hexane and they said it formes hexane and 3 other molecules
    C didn't make enough carbon or was it hydrogen atoms

    do any of you know if it matters which side you put your dot in the Cl free radical?

    Nope, it dosen't matter, only matters really with carbons, where you have to put the dot next to the carbon atom.

    You needed to make a total of 3 molecules of another compound and pentene. All of them added correctly but the number of molecules were different. Also C was the only one without a pentene but another compound I believe.

    it was 1 molecule of hexane the question said and 3 other molecules
    A didnt have hexane and and they added up i checked twice

    this doesnt even matter either, but you should probably do it like you said

    Are you sure? Because I remember checking that A does have that other compound and it also had 3 molecules of the other compound but C only had two products. I'm not sure, if anyone else can back any other answers that would be great.

    there was, forming CF3CH3 from CHF2CH3 and flourine in a free-radical substitution. you had to give two propagation steps. what did you guys get for this? i only got the first one, as CHF2CH3 + F. --> CF2CH3. + HF

    the next step is f2 + cf2ch3' -> cf3ch3 + f'

    Then its .CF2CH3+F2 -> CF3CH3 + F.
