In a laboratory demonstration of the 'nylon rope trick', Nylon-6,10 is synthesized at the interface of two immiscible solutions by reacting decanedioyl dichloride, ClOC(CH2)8COCl\text{ClOC(CH}_2\text{)}_8\text{COCl}ClOC(CH2)8COCl, dissolved in an organic solvent, with hexane-1,6-diamine, H2N(CH2)6NH2\text{H}_2\text{N(CH}_2\text{)}_6\text{NH}_2H2N(CH2)6NH2, dissolved in water.
Which small molecule is eliminated during this condensation polymerization reaction?
CO2\text{CO}_2CO2
H2O\text{H}_2\text{O}H2O
HCl\text{HCl}HCl
NH3\text{NH}_3NH3
