Two equivalents of molecular halogen will react with and add to an alkyne. Complete the mechanism and draw the organic product.

Include all lone pairs and nonzero formal charges.

Answer:

The drawing of the mechanism and the organic product is shown below.

Explanation:

Alkynes react with bromine to form a dihaloalkene (with an equivalent of the halogen) or a tetrahaloalkane derivative (with two equivalents of the halogen), which is this case. The triple bond adds two halogen molecules as shown in the drawing, an anti addition occurring.

I think that rock from the mantle is added to the edges of both plates at
soldi70 [24.7K]

Answer:

The Earth’s lithosphere, which includes the crust and upper mantle, is made up of a series of pieces, or tectonic plates, that move slowly over time.

A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust. The Mid-Atlantic Ridge and Pacific Ring of Fire are two examples of divergent plate boundaries.

Compare and contrast the compositions of binary ionic and binary molecular compounds
ICE Princess25 [194]
<span>Both are composed of two elements (that means binary).
Ionic is composed of two ions, metallic cation-positive ions, and nonmetallic anion - negative ions. For example NaCl (sodium-chloride).
Molecular compounds are composed of two nonmetallic elements. For example HCl (hydrochloric acid).</span>

What happens to the energy needed to remove an electron as the atomic number increases across a period?
lora16 [44]

Answer:

In general, the energy needed to remove an electron (the ionization energy) increases as the atomic number increases across a period.

Explanation:

Each additional proton increases the attraction between the nucleus and the electron.

Thus, it takes more energy to remove an electron as you add extra protons.
