At 25 °c, what is the hydroxide ion concentration, [oh–], in an aqueous solution with a hydrogen ion concentration of [h ] = 3.0

chubhunter [2.5K]

As,

Water has a pkw=14

so it can be represented as,

[H+] [OH-] = 1*10^-14

If [H+] = 3*10^-5M

[OH-] = (1*10^-14) / ( 3*10^-5)

[OH-] = 3.3*10^-9 M

Name the cycloalkanes with molecular formula c6h12 that have a 3-membered ring and two substituents.

Tanzania [10]

Answer:

1-ethyl-2-methyl cyclopropane.

Explanation:

The structure of the molecule will be as shown in the attached image.

The molecular formula of the compound is C₆H₁₂.

It has 3 membered ring with 3 C atoms and two substituents one of them with one C atom (methyl) and the other with 2 C atoms (ethyl).

The ring consist of 3 C atoms, so its name is cyclo propane.

We numbering the atoms of the ring that give the ethyl substituent the low no. (1) and then methyl group take no. (2).

<em>Thus, the name of the compound is 1-ethyl-2-methyl cyclopropane.</em>
