Propose a structure for an aromatic hydrocarbon, C9H12, that can form two C9H11Cl products on substitution of a hydrogen on the
Crank

Answer:

Explanation:

From the given study,

the molecular formula of the given aromatic compound = C9H12

the first process we suppose to carry out is to calculate the double bond equivalence.

So, the double bond equivalence DBE = {N_C+1-(\dfrac{(N_H+N_{Cl})-N_H}{2})  }

DBE = {9+1-(\dfrac{(12+0)-0}{2})  }

DBE = 4

Hence, the aromatic compound possesses 4 double bonds, this signifies that the might be a presence of benzene ring.

The substitutional products of the aromatic hydrocarbon C9H12 can be seen in the attached file below.

The alkane with six carbon atoms is called hexane. butane. butene. heptane. none of these choices is correct.
Mkey [24]

Option(A) is the correct answer.

The alkane with six carbons is called hexane.

<h3>What are the potential hazards of hexane?</h3>

Hexane is used as a special-purpose solvent, a cleaning agent, and to extract edible oils from seeds and vegetables. Humans who are acutely (short-term) inhaled high quantities of hexane have moderate central nervous system (CNS) symptoms such giddiness, nausea, headache, and dizziness. Humans who are exposed to hexane in the air <u>over an extended period of time</u> may develop polyneuropathy, which manifests as numbness in the extremities, muscle weakness, impaired vision, headaches, and tiredness. Rats have also displayed neurotoxic consequences. Hexane's potential to cause cancer in both humans and animals is unknown. Hexane has been categorized by the EPA as Group D, not classifiable as a human carcinogen.

Write the symbol for nitrogen which has 9 neutrons<br><br>How do I solve this?
diamong [38]
If you mean lewis dot symbol you need a nuclide you get the number of proton (z) its equal to electrons since the atom is nutral then you make the elctron configuraion after that you take the number of electrons on the outer energy level( ex:k²L² in this case its the 2 on the L)and if you have 7 electrons and the atom is nitrogen so it becomes

Place the following compounds in order of increasing strength of intermolecular forces. HF H2 CH3Cl
Scorpion4ik [409]

Answer:

H2 < CH3Cl < HF

Explanation:

The intermolecular forces are the forces that bond the molecules together in a substance. There are three types of these forces:

  1. Dipole induced -dipole induced, or London dispersion -> Is the weakest and is presented in nonpolar molecules, in which a dipole is induced and so the molecules are joined together;
  2. Dipole-dipole -> Is stronger than the London dispersion and occurs in a polar molecule. In this case, the dipole already exists (partial positive and negative charges), so the poles are attracted;
  3. Hydrogen bond -> It's the strongest and is formed when the hydrogen is bonded with a higher electronegativity element (F, O, and N).

So, the molecule of H2 is linear and formed by the same element, so, is nonpolar, and has London dispersion forces. The molecule of CH3Cl has 3 nonpolar bonds (C-H), and one polar bond (C-Cl), so it's polar and has dipole-dipole forces. And the HF molecule has hydrogen bonds.

*A polar bond is a bond formed by elements with different electronegativities.

How many water molecules are produced when 5.2g O2 are reacted
gtnhenbr [62]

Answer:

Total number of water molecules produced after the reaction is 1.956×10^22 molecules of water.

Explanation:

By the reaction

H2+ 1/2 O2 → H2O

Moles of O2 = 5.2\32

⇒1 mole of O2 produce 1  mole of H2O

  1 mole O2 will produce 2 mole  of H2O

Therefore, 5.2\32 mole will produce {2}\times{\frac{5.2}\times{32}}

⇒ Molecules of H2O  will be

         {2}\times{\frac{5.2}{32}} = \frac{x}{{6.02}\times{10^23}}

= 1.956×10^22 moleculesof H2O.
