Can someone tell me what product is formed when -

acetylene and oxygen react
3-methylbutyne reacts with hydrogen
chloroethane reacts with hydroxide ions

1 answer

C2H2 + O2 ---> CO2 + H2O (assuming complete oxidation)
H-C---C-CH(CH3-CH3 + H2 ---> 3-methylbutene or 2-methylbutane, depending on the degree of hydrogenation (reduction)
CH3CH2Cl + NaOH ---> NaCl + _____?
