Why is 1-methylhexane not a legitimate name for a compound?

Answer:

It is not a legitimate chemical name because the methyl group on carbon 1 increases the length of the carbon chain to seven carbon atoms thus making the parent compound heptane

Explanation:

Chemical compounds are named according to rules in the IUPAC nomenclature.

In naming organic compounds, parts of rules is to find out the parent or root compound. This is determined by finding out the longest carbon chain and then checking if it contains single or multiple bonds. (that is if it is an alkane- with single bonds, alkene-with double bonds or an alkyne- with triple bonds)

From the question the parent or root name is an alkane containing 6 (Hex-) carbon atoms, while the methyl group is substituent

(CH₃)-CH₂-CH₂-CH₂-CH₂-CH-CH₃

However the alkyl substituent on carbon 1 increases the the length of the carbon chain to 7 (Hept-) instead of 6. Hence the correct IUPAC nomenclature is heptane and not 1-methylhexane.

The number of C atoms in 0.524 moles of C is 3.15 atoms.

The number of $SO_2$ molecules in 9.87 moles $SO_2$ is 59.43 molecules.

The moles of Fe in 1.40 x $10^{22}$ atoms of Fe is 0.23 x $10^{-1}$

The moles of $C_2H_6O$ in 2.30x $10^{24}$ molecules of $C_2H_6O$ is 3.81.

<h3>What are moles?</h3>

A mole is defined as 6.02214076 × $10^{23}$ of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

A. The number of C atoms in 0.524 mole of C:

6.02214076 × $10^{23}$ x 0.524 mole

3.155601758 atoms =3.155 atoms

B. The number of $SO_2$ molecules in 9.87 moles of $SO_2$ :

6.02214076 × $10^{23}$ x 9.87

59.4385293 molecules= 59.43 molecules

C. The moles of Fe in 1.40 x $10^{22}$ atoms of Fe:

1.40 x $10^{22}$ ÷ 6.02214076 × $10^{23}$

0.2324754694 x $10^{-1}$ moles.

0.23 x $10^{-1}$ moles.

D. The moles of $C_2H_6O$ in 2.30x $10^{24}$ molecules of $C_2H_6O$ :

2.30x $10^{24}$ ÷ 6.02214076 × $10^{23}$

3.819239854 moles=3.81 moles

Given the following equation, what is the correct form of the conversion factor needed to convert the number of moles of O₂ to t

djverab [1.8K]

Answer : The correct option is (c) $\frac{2\text{ mole of }Fe_2O_3}{3\text{ mole of }O_2}$

Explanation :

The given balanced chemical reaction is,

$4Fe(s)+3O_2(g)\rightarrow 2Fe_2O_3(s)$

From the balanced chemical reaction, we conclude that

As, 3 moles of $O_2$ react to give 2 mole of $Fe_2O_3$

So, 1 mole of $O_2$ react to give $\frac{2\text{ mole of }Fe_2O_3}{3\text{ mole of }O_2}$ moles of $Fe_2O_3$

Thus, the conversion factor needed to convert the number of moles of $O_2$ to the number of moles of $Fe_2O_3$ produced is $\frac{2\text{ mole of }Fe_2O_3}{3\text{ mole of }O_2}$

Hence, the correct option is (c) $\frac{2\text{ mole of }Fe_2O_3}{3\text{ mole of }O_2}$
