Hi,
I recently had an organic chemistry lab in which we converted 3-methyl-3-pentanol into 3-chloro-3-methylpentane with HCL and then purified the pentane.  Calcium chloride was added to dehydrate it and then NaHCO3, and then MgSO4, all of which were filtered out.  Finally the product was distilled (it had a boiling point of around 110 Celsius) and a blue litmus strip was put to the tube on the vacuum filtration of the simple distillation apparatus.  It tested as an acid.  I was wondering if anyone knew why that would happen. 
It seems like all the HCL should have been filtered out that this point so I was thinking that it could have been CO2 gas coming out but I couldn't find any reference to something like that occurring in the book.  Any ideas?

What would the products be if this compound underwent an elimination reaction?  What would the mechanism be?

hi,
I think in the treatment process won't happen side effects,It seems like all the HCL should have been filtered out ,if tested as an acid,May material  itself character.
