Can someone tell me what product is formed when -

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

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 + _____?

Sure! I'd be happy to help explain.

1. Acetylene and oxygen react:
To determine the product formed, we need to know the chemical equation for the reaction between acetylene and oxygen. The chemical equation would look like this:

2 C2H2 + 5 O2 -> 4 CO2 + 2 H2O

In this reaction, acetylene (C2H2) reacts with oxygen (O2) to produce carbon dioxide (CO2) and water (H2O) as products.

2. 3-methylbutyne reacts with hydrogen:
Again, we need to know the chemical equation for the reaction between 3-methylbutyne and hydrogen. The balanced chemical equation would look like this:

C6H10 + 6 H2 -> C6H14

In this reaction, 3-methylbutyne (C6H10) reacts with hydrogen (H2) to produce 2-methylpentane (C6H14) as the product.

3. Chloroethane reacts with hydroxide ions:
To determine the product formed, we need to know the chemical equation for the reaction between chloroethane and hydroxide ions. The balanced chemical equation would look like this:

C2H5Cl + OH- -> C2H5OH + Cl-

In this reaction, chloroethane (C2H5Cl) reacts with hydroxide ions (OH-) to produce ethanol (C2H5OH) and chloride ions (Cl-) as products.

Remember, to determine the products of a reaction, it's important to have the correct balanced chemical equation.
