Answer:

<u><em>1. The air boiled out of water as steam is rich in water vapor, </em></u><em><u>H₂O</u></em><u><em>(g)</em></u>

<u><em></em></u>

<u><em>2. Benzene reacts with hydrogen in the presence of nickel catalyst at 180°C to give cyclohexane.</em></u>

Explanation:

<em></em>

1. When water boils liquid water passes to gaseous phase.

Water in gaseous phase is named water vapor or steam.

This happens around 100ºC, depending on the atmospheric pressure.

The air that is around the boiling water will carry that steam, becomind an air rich in water vapor, H₂O(g)

2. Benzene has chemical formula C₆H₆.

It is a cyclic unsaturated hydrocarbon. Benzene contains 3 double bonds.

When unsaturated hydrocarbons are heated in the presence of nickel catalyst, the double bonds are broken, forming single bonds and adding the needed hydrogen to the chain: one to each carbon that had a double bond transformed into single bond.

Thus, the product of the catalytic hydrogenation of benzene, C₆H₆,  is cyclohexane, C₆H₁₂

There are four different starting molecules that one might use to synthesize the illustrated alkyl halide as the major product u
Mkey [24]

Answer:

Explanation:

An electrophilic addition reaction occurs when an electrophile attacks a substrate, with the end result being the inclusion of one or many comparatively straightforward molecules along with multiple bonds.

In the given question, the hydrogen bromide provides the electrophile while the bromide is the nucleophile. The mechanism proceeds with the attack of the electrophile on the carbon, followed by deprotonation. This process is continued with a formation of carbocation and the bromide(nucleophile) finally bonds to the carbocation to form a stable product.

The first diagram showcases the possible various starting molecules for the synthesis while the second diagram illustrates their mechanism.
