What is the name of this hydrocarbon? 2-dimethylyne 2-methylbutane 4-methylbutene 4,3-methylbutyne 4,4-methylbutane

Alisiya [41]

You have shown no structure, still we can work out for the answer :).

First Option: <span>2-dimethylyne: This name is incorrect, because it does not contain any parent chain name.

Second Option: </span><span>2-methylbutane: I have drawn its structure below, compare it with your structure.

Third Option: </span>4-methylbutene:<span> I have drawn the structure for this name. But this name is also against IUPAC rules, and its correct name is 1-Pentene.

Fourth Option: </span><span>4,3-methylbutyne: Again incorrect name, 4,3 are two positions, but here only one substituent is given (methyl). I have drawn structure of 3,4-Dimethylbutene, this name is incorrect, and the correct name for this compound is 3-Methyl-1-pentene.

Fifth Option: </span><span>4,4-methylbutane: Again incorrect name, 4,4 means at 4 position two substituents, but in name only methyl is given. Anyhow lets make it two and draw a structure, for 4,4-Dimethylbutane. Ooops!! This name is also incorrect, and the correct name for this compound is 2-Methylpentane.

Result:
Among all options only, option B (2-Methylbutane) is correctly named, and this will be the correct name for the structure given to you. </span>

How to do 4 please it is a quick question

Kay [80]

Answer

a) Group 16

b) Group 1

c) Group 15

d)

e)

f) Sodium

g) Oxygen

h) Phosphorus

Procedure

Using the periodic table below identify the elements. The periodic table organizes elements in a way that reflects their number and pattern of electrons. The table places elements into columns—groups—and rows—periods.

An element’s column number gives information about its number of valence electrons and reactivity. In general, the number of valence electrons is the same within a column and increases from left to right within a row. Applies only for groups 1,2, 13-18 (remembering that from 13 to 18 the last number is the valence).

A nuclear fission reaction has mass difference between the products and the reactants of 3.86 g. Calculate the amount of energy

iris [78.8K]

<u>Answer:</u> The amount of energy released by the reaction is $3.47\times 10^{14}J$

<u>Explanation:</u>

To calculate the energy released, we use Einstein equation, which is:

$E=\Delta mc^2$

where,

$\Delta m$ = difference between the masses of products and reactants = 3.86 g = 0.00386 kg (Conversion factor: 1 kg = 1000 g)

c = speed of light = $3\times 10^8m/s$

Putting values in above equation, we get:

$E=(3.86\times 10^{-3}kg)\times (3\times 10^8m/s)^2$

$E=3.47\times 10^{14}J$

Hence, the amount of energy released by the reaction is $3.47\times 10^{14}J$

What is the approximate volume of 19g of fluorine gas at a pressure of 4.0 atmospheres and a temperature of 127o C?

mr Goodwill [35]

Answer:

V = 8.21 L

Explanation:

Given data:

Volume of fluorine = ?

Mass of fluorine = 19 g

Pressure = 4.0 atm

Temperature = 127 °C(127+ 273 =400 K)

Solution:

Number of moles of fluorine:

Number of moles = mass/molar mass

Number of moles = 19 g/ 19 g/mol

Number of moles = 1 mol

PV = nRT

V = nRT/P

V = 1 mol ×0.0821 atm. L. mol⁻¹. k⁻¹ × 400 K/ 4 atm

V = 32.84 L/ 4

V = 8.21 L
