Select the single best answer. Explain why (CH3)2CHCH(Br)CH2CH3 reacts faster than (CH3)2CHCH2CH(Br)CH3 in an E2 reaction, even

though both alkyl halides are 2°. The second structure has more hydrogens attached to the β carbons than the first structure. The first structure has more hydrogens attached to the β carbons than the second structure. The major and minor products formed from the first structure have more alkyl groups on the C═C than those formed from the second structure. The major and minor products formed from the second structure have more alkyl groups on the C═C than those formed from the first structure.

Answer:

The major and minor products formed from the first structure have more alkyl groups on the C═C than those formed from the second structure

Explanation:

When we consider the structures of the major and minor products from the dehydrohalogenation of structure 1 by E2 mechanism, it is easy to see that the both products are highly substituted by alkyl groups. It is a fact in organic chemistry that the more substituted an alkene is the more stable it is and the more quickly it is formed; Hence the answer

How do you determine the number of electrons an atom will gain or loose
enyata [817]

In general, metals will lose electrons to become a positive cation and nonmetals will gain electrons to become a negative anion. Hydrogen is an exception, as it will usually lose its electron. Metalloids and some metals can be can lose or gain electrons. This is not always true, as elements such as nitrogen can lose electrons to become positive. When an ionic compound forms, the more electronegative element will gain electrons and the less electronegative element will lose electrons. Hope this helps :)

If I have 13 protons and 12 electrons what is my charge?
Mnenie [13.5K]

Answer:

The charge would be +1

Explanation:

Protons have a positive charge while electrons have a negative charge. Therefore, it's simple subtraction. In every case, subtract the number of electrons from the number of protons.

13 - 12 = 1

Therefore the charge is +1

Here's one more example:

If the element chromium (Cr) has 24 protons and 28 electrons, what is its charge? Remember that protons have a positive charge and electrons have a negative charge.

24 - 28 = -4

Charge = -4

It would be written as followed when associating charge with a specific element: Cr^{-4}

If an element has a neutral charge, that means the number of protons and neutrons are the same. If you look at the periodic table of elements, all of the elements listed have a neutral charge. The 0 isn't showed in the corner because it isn't necessary.

Bonus Information:

This isn't related to your question, but I've come across confusions when it comes to particles. Remember that protons (+) and electrons (-) are the only particles that have a charge, therefore, as it says in it's name, neutrons are neutral or have no charge. Neutrons do not contribute to charge, but they do contribute to the <em>mass</em> of an atom. So the number of protons added to the number of neutrons equate to the mass of an atom. Electrons have mass, but it's so miniscule and insignificant that it doesn't even contribute to the overall mass of the atom, so don't count those.

Remember:

C = p - e

M = p + n

C = atomic charge, M = atomic mass, p =protons, n = neutrons, e = electrons

I hope this helps!
