As chemistry, upcoming test please help!?

Question

Both 2-chloropropane and 2-iodopropane form the same organic product in the reaction with aqueous silver nitrate what is the structural formula of this product.

Also why when calculating the enthalpy change of combustion is it simply Q=CdeltaT = and then divide by moles rather than Q=cmdeltaT as it is for the enthalpy change of formation?

thanks a lot

Answer 1

The organic product is propan-2-ol in both cases.

Q = m x c x delta T is always used when you have a calorimeter. It doesn't matter which enthalpy change you are measuring.
