waht is the IUPAC name of CH2=CH2 + H2O yields (and on top of the arrow sign is H3PO4) product? what is the answer?

ethanol

The reaction you mentioned, CH2=CH2 + H2O (with H3PO4 as a catalyst), results in the formation of an alcohol. Here is the step-by-step process to determine the IUPAC name of the product:

Step 1: Write the structural formula of CH2=CH2:
H2C=CH2

Step 2: Identify the product formed by adding water (H2O) to CH2=CH2:
H2C=CH2 + H2O → CH3-CH2-OH

Step 3: Determine the IUPAC name for the product, CH3-CH2-OH:
CH3: methyl
CH2: ethyl
OH: alcohol

Therefore, the IUPAC name of the product is ethanol.

To determine the IUPAC name of the product resulting from the reaction CH2=CH2 + H2O (catalyzed by H3PO4), we first need to consider the type of reaction taking place.

In this case, we have an addition reaction occurring between an alkene (CH2=CH2) and water (H2O). The reaction is catalyzed by phosphoric acid (H3PO4), which acts as an acid catalyst to protonate the alkene and initiate the addition.

The first step in this reaction involves the protonation (addition of a proton) of the alkene by H3PO4:

CH2=CH2 + H3PO4 -> CH3-CH2+-H2PO4

After the protonation step, the addition of water takes place, resulting in the formation of an alcohol:

CH3-CH2+-H2PO4 + H2O -> CH3-CH2-OH + H3PO4

The IUPAC name of the product CH3-CH2-OH is ethanol.

Therefore, the product formed from the reaction CH2=CH2 + H2O (catalyzed by H3PO4) is ethanol.
