Draw the most stable conformation of 3-isopropyl-1,1dimethylcyclohexane Please show me which one is the isopropyl and the dimeth
Andrei [34K]

The most stable conformation of 3-isopropyl-1,1dimethylcyclohexane equatorial ethyl group (more stable).  The stability of ethylcyclohexane's equatorial conformer exceeds that of its axial conformer by 7.4 kJ/mol.

According to the previous section, the chair conformation with the equatorial methyl group is more stable because it reduces steric repulsion, and as a result, the equilibrium favors the more stable conformer. Strongly favoring the equatorial shape is methylcyclohexane. The methyl group is in close proximity to the axial hydrogens in the axial conformation, which has an energetically unfavorable effect known as a 1,3-diaxial interaction. The methyl group prefers the equatorial shape as a result.  The conformation of ethylcyclohexane in which the ethyl group is in the equatorial position is the most stable.

MAXImum [283]

Answer:

Sulfuric acid + Zinc = reactant

Zinc sulfate + hydrogen = product

Lead oxide + carbon = reactant

lead + carbondioxide = product

Explanation:

Chemical equation:

Sulfuric acid + Zinc → Zinc sulfate + hydrogen

H₂SO₄ + Zn → ZnSO₄ + H₂

In this reaction sulfuric acid and zinc react to produce the zinc sulfate and hydrogen. That's why sulfuric acid and zinc are reactant. While zinc sulfate and hydrogen are products.

2nd reaction:

Lead oxide + carbon   →  lead + carbondioxide

2PbO + C →  2Pb + CO₂

In this reaction Lead oxide and carbon  react to produce the lead and carbondioxide. That's why Lead oxide and carbon are reactant. While lead and carbondioxide are products.
