Identify the intermediate in the halogenation of alkanes.a) Anionb) Cationc) Radicald) Dimer
Alex_Xolod [135]

Answer: Option C - Radical

Explanation:

A radical is a chemical specie carrying a lone electron. In the halogenation of alkanes: take Methane CH4 as the alkane, and Chlorine Cl as the halogen.

The step by step halogenation process is as follows:

CH4 + Cl2 --> CH3• + HCl + Cl•

CH3• + Cl2 --> CH3Cl + HCl

CH3Cl + Cl2 --> CH2Cl2 + HCl + Cl•

CH2Cl2 + Cl2 --> CHCl3 + HCl

CHCl3 + Cl2 --> CCl4 + HCl + Cl•

Chlorine molecule attack methane knocking off an hydrogen atom from it and forming a methyl radical (CH3•), that is subsequently attack by another chlorine molecule. This cycle repeats itself, until no hydrogen atom is available for substitution by the highly reactive chlorine radical.

Note: no cation or anion is formed in the halogenation process

Suppose you have a 0.10 M solution of AlBr3. What is the concentration of each ion? A. 0.10 M Al3+ ions and 0.30 M Br- ions B. 0
podryga [215]

<u>Answer:</u> The concentration of Al^{3+} ions is 0.10 M and that of Br^- ions is 0.30 M

<u>Explanation:</u>

We are given:

Concentration of AlBr_3 = 0.10 M

The chemical equation for the ionization of aluminium bromide follows:

AlBr_3\rightarrow Al^{3+}+3Br^-

1 mole of aluminium bromide produces 1 mole of aluminium ions and 3 moles of bromide ions

So, concentration of aluminium ions = 0.10 M

Concentration of bromide ions = [(3\times 0.1)]=0.3M

Hence, the concentration of Al^{3+} ions is 0.10 M and that of Br^- ions is 0.30 M

If a sulfur atom gained 3 protons what atom would be formed?
Scilla [17]

Answer:

The stable ion the sulfur would form is the sulfide ion,

Explanation:

When any atom accept electrons it converts into negative ion/an anion. So it will change into Z 3− after gaining 3 electrons.
