Answer:

c. 5-chloro-3-methyl-2-hexanone

Explanation:

The IUPAC nomenclature of alkanes are given as follows:

Select the longest possible carbon chain.
For the number of carbon atom, we add prefix as 'meth' for 1, 'eth' for 2, 'prop' for 3, 'but' for 4, 'pent' for 5, 'hex' for 6, 'sept' for 7, 'oct' for 8, 'nona' for 9 and 'deca' for 10.
A suffix '-ane' is added at the end of the name.
If two of more similar alkyl groups are present, then the words 'di', 'tri' 'tetra' and so on are used to specify the number of times these alkyl groups appear in the chain.

For any substituent attached, the numbering is done according to the priority of the functional group which is:-

Carboxylic Acids > Acid Anhydrides > Esters > Acyl Halides > Amides > Nitriles > Aldehydes > Ketones > Alcohols > Thiols > Amines > Ethers > Sulphides > Alkenes > Alkynes > Alkyl Halides > Nitro > Alkanes

Thus,

Numbering is shown below. The long chain is 6 membered ring having substituents ketone at C-2, methyl group at C-3 and chloro bond at C-5

The name is:-

<u>c. 5-chloro-3-methyl-2-hexanone</u>

A test done under standard conditions is referred to as what in chemistry?

elena-s [515]

The answer for the above question is the control. A control is that particular test that is done under standard conditions. Therefore, a controlled experiment is an experiment is where one test is done under standard or normal conditions, and all the other tests compare to the standard conditions. The standard conditions are majorly a temperature of 273 K or 0 degrees Celsius, and a pressure of 1 atm or 760 mmHg.

A gas cylinder of volume 5.00 l contains 1.00 g of ar and 0.500 g of ne. the temperature is 275 k. find the partial pressure of

amid [387]

<span>11.3 kPa The ideal gas law is PV = nRT where P = Pressure V = Volume n = number of moles R = Ideal gas constant (8.3144598 L*kPa/(K*mol) ) T = Absolute temperature We have everything except moles and volume. But we can calculate moles by starting with the atomic weight of argon and neon. Atomic weight argon = 39.948 Atomic weight neon = 20.1797 Moles Ar = 1.00 g / 39.948 g/mol = 0.025032542 mol Moles Ne = 0.500 g / 20.1797 g/mol = 0.024777375 mol Total moles gas particles = 0.025032542 mol + 0.024777375 mol = 0.049809918 mol Now take the ideal gas equation and solve for P, then substitute known values and solve. PV = nRT P = nRT/V P = 0.049809918 mol * 8.3144598 L*kPa/(K*mol) * 275 K/5.00 L P = 113.8892033 L*kPa / 5.00 L P = 22.77784066 kPa Now let's determine the percent of pressure provided by neon by calculating the percentage of neon atoms. Divide the number of moles of neon by the total number of moles. 0.024777375 mol / 0.049809918 mol = 0.497438592 Now multiply by the pressure 0.497438592 * 22.77784066 kPa = 11.33057699 kPa Round the result to 3 significant figures, giving 11.3 kPa</span>

Between nitromethane (CH3-NO2) and methyl nitrite (CH3-0-NO), which has the higher boiling point? Explain the reason in less tha

kondor19780726 [428]

Answer:

$CH_3NO_2$ has higher boiling point

Explanation:

$CH_3NO_2$ has higher boiling point because in $CH_3NO_2$ , $NO_2$ has a very strong dipole and we know that whenever there is dipole-dipole interaction then boiling point increases. On the other hand in $CH_3-O-NO$ the NO group has not so strong dipole which weakens its boiling point

So the boiling point of $CH_3NO_2$ is higher than the boiling point of $CH_3-O-NO$
