Please use the E/Z notation when specifying stereochemistry remembering to use parentheses and a dash. Reminder - the double bon

d takes precedence over alkyl groups when numbering the parent. (E)-5-bromo-5-ethylhept-2-ene when combined with NaOCH2CH3.

Answer:

(E)-5-ethylhepta-2,4-diene

Explanation:

The  (E)-5-bromo-5-ethylhept-2-ene will undergo an E2 reaction. The ethoxide (⁻OCH₂CH₃) will deprotonate at the allylic position so that a conjugated diene results, which is more stable than a non-conjugated diene.

The stereochemistry in the name of the final product is indicated for only one double bond since the other has two identical groups on it.

given that 32.0g sulphur contains 6.02×10^23 sulphur atoms,how many atoms are there in 2.70g of aluminum​
dangina [55]

Answer:

6.022 × 10²² atoms

Explanation:

Generally 1 mol of any element contains 6.02×10^23  atoms. The number 6.022 × 10²³ is known as Avogadro's number.

Mass of Aluminium = 2.70g

Molar mass = 27g/mol

Number of moles = Mass / Molar mass = 2.70 / 27 = 0.1 mol

1 mol =  6.022 × 10²³

0.1 mol = x

x = 6.022 × 10²³ * 0.1 = 6.022 × 10²² atoms

which of the following testable questions will provide evidence that elements in the same group have similar properties?
Usimov [2.4K]

The testable question which will provide evidence that elements in the same group have similar properties is valency

<h3>What is the valency?</h3>

In essence, how many electrons are present in their outermost shell.

Valency and Groups in the periodic table, elements are arranged in order of their atomic numbers and hence, the periodic table is a systematic arrangement of elements in an array of vertical columns called Groups and horizontal arrays called Periods.

  • Complete question here:

which of the following testable questions will provide evidence that elements in the same group have similar properties A. Valency B. Orbit C. Group D. Period

Since, the reactive capacities of elements is dependent on the number of electrons on its outermost shell, we can conclude on this note that, Elements in the same group have similar properties.

The fifth element in group 7 in astatine would you expect it to be gas, liquid, or solid? why?
Ymorist [56]

Answer:

solid

Explanation:

Melting and boiling points of Group 7 elements State at room temperature Room temperature is usually taken as being 25°C. At this temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine and astatine are solids. There is therefore a trend in state from gas to liquid to solid as you go down the group.
