Need Help with three tough questions! Paper due tomorrow

I have a question about C₄H₈Cl₂

A compound with the molecular formula C₄H₉Cl reacts with chlorine ( ultraviolet light is used as the catalysator). I would like to know wich structure the compound (C₄H₉Cl) has if it can react into exactly three different dichloride compoundes?

Is it 1-chlorobutane, 2-chlorobutane, 1-chloro-2-methylpropane or 2-chloro-2-methylpropane? I think it´s 2-chloro-2-methylpropane, but I´m not sure.

thanks for your help!

Also-

I have a though question about ethanol. The ethanol in a 750 cm3 wine bottle has oxidated into acetic acid. How much NaHCO₃ do you need to neutralize the acid. The alcohol concentration in the wine bottle is 20% and the density of ethanol is 0,789 grams/cm3.

With these reactions:

1. 2 C₂H₅OH + O₂ = 2 CH₃CHO + 2 H₂O

2. 2 CH₃CHO + O₂  2 CH₃COOH

3. CH₃COOH + NaHCO₃ = H₂O + NaCO₃ + CO₂

I have calculated that it will require 211 g of NaHCO₃ to neutralize the acetic acid in the wine bottle. Does that sound about right?

And-

Can octane and ethanol have the same amount of carbondioxide discharge when incinirated?

The "energiamount" of octane is 5470 000 Joule/molar
and ethanol is 1367 000 Joule/molar
