Answer:

I couldn't find options online for your question. But I can explain a little bit about it so you can identify the answer for yourself.

A binary ionic compound is made up of ions that have two different elements.

Of these two ions, one must be a metal and the other a nonmetallic.

The metallic atom will lose electrons, becoming a positive ion (cation), and the non-metallic atom will gain electrons, transforming into a negative ion (anion). Between them there is a very strong electrostatic attraction that is what holds them together.

Here are some examples of these types of compounds:

Sodium oxide: Na2O

Calcium hydroxide: Ca (OH) 2

Aluminum hydride: AlH3

Hydrochloric acid: HCl

Which of the following correctly describes a compound?

Nutka1998 [239]

A compound is a pure substance formed by the chemical combination of two or more different elements.

A compound may be splitted into simpler substances by chemical reactions, and has different properties to those of the elements that form it.

The composition of a compound is fixed: every piece of a compound has the same kind of atoms, bonded in the same way and proportion.

Some examples of compounds are H₂O, NaCl, H₂O₂, CH₃COOH. As you see, they have a chemical formula which states the kind and number of the atoms that form them.

They are different to mixtures, which are formed by two or more compounds, in a variable proportion, and can be separated by physical media. Some examples of mixtures are the solutions (e.g. NaCl dissolved in H₂O), and some solid mixtures (e.g. a mixture of marbles and sand).

Draw the major organic product in the reaction scheme below. Be sure to clearly show stereochemistry (if applicable).

Juliette [100K]

Answer:

see explanation below

Explanation:

You are missing the reaction scheme, but in picture 1, I found a question very similar to this, and after look into some other pages, I found the same scheme reaction, so I'm gonna work on this one, to show you how to solve it. Hopefully it will be the one you are asking.

According to the reaction scheme, in the first step we have NaNH2/NH3(l). This reactant is used to substract the most acidic hydrogen in the alkine there. In this case, it will substract the hydrogen from the carbon in the triple bond leaving something like this:

R: cyclopentane

R - C ≡ C (-)

Now, in the second step, this new product will experiment a SN2 reaction, and will attack to the CH3 - I forming another alkine as follow:

R - C ≡ C - CH3

Finally in the last step, Na in NH3 are reactants to promvove the hydrogenation of alkines. In this case, it will undergo hydrogenation in the triple bond and will form an alkene:

R - CH = CH - CH3

In picture 2, you have the reaction and mechanism.
