Complete Question

The complete question is shown on the first uploaded image

Answer:

The correct option is A

That is 2,4,5-Trimethyl-4-propylheptane

Explanation:

Looking at the structure the longest carbon chain is 7 as shown on the second uploaded image

Also from the diagram of the structure we can identify that is longest chain has 3 methyl group attachment and one propyl group  attachment  

 Now going through this longest chain the numbering of this attachment them the lowest number is the correct way so as we can see

  2,4,5-Trimethyl-4-propylheptane  gives the lowest numbering compared to 3,4,6-Trimethyl-4-propylheptane so the correct IUPAC names is 2,4,5-Trimethyl-4-propylheptane

"Write the balanced chemical equation for the neutralization reaction that occurs when an aqueous solution of hydrochloric acid
timurjin [86]

Answer:

KOH(aq) + HCl(aq) ——-> KCl(aq) + H2O(l)

Explanation:

A neutralization reaction is the chemical reaction between an acid and an alkali to yield salt and water only.

In this particular question, the acid is hydrochloric acid while the alkali is potassium solution. We now write the equation of reaction as follows:

KOH(aq) + HCl(aq) ——-> KCl(aq) + H2O(l)

The salt formed here is KCl otherwise called potassium chloride
