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

A 220.0-mL sample of helium gas is in a cylinder with a movable piston at 105 kPa and 275K. the piston is pushed until the sampl
nignag [31]
Using the general gas equation:

P₁V₁/T₁ = P₂V₂/T₂

(105*220)/275 =   (P₂*95)/310

(105*220)*310/275  = P₂*95

 (105*220*310)/(275*95)  =  P₂

       274.11        =  P₂

       P₂  = 274.11 kPa

       New Pressure =  274.11 kPa
