UNIT 14 ASSIGNMENT A: APPLICATIONS OF ORGANIC CHEMISTRY


14A



1. FUNCTIONAL GROUPS:
- Halogenoalkanes are hydrocarbon that typically contains single halogen as well as
solely single carbon-carbon bond (S). however, they’re employed in many different
applications, which including fire extinguishant, flame retardant, solvents,
refrigerants, propellant, and medicines.

Reactivity:
Halogenoalkanes cannot combine with almost anything except if the links between carbon
and halogen are dissolved, and when the bonds are broken, the halogen is replaced by
another chemical molecule in a process known as a substitution reaction. Forming the
relationship becomes increasingly harder as you progress through the group. Nucleophilic
substitution happens in halogenoalkanes since electro gravity causes the carbon atom to
gain a positive charge, and since the carbon has a positive charge, nucleophiles replace the
halogens that were previously linked to the carbon. Halogenoalkanes must be present in the
appearance of sodium or potassium hydroxide for such a reaction when it is used to
eliminate a hydrogen atom from 2-bromopropane together with the bromine as well as the
carbons which lost the bromine as well as hydrogen that are between two carbons form a
double bond after the discharge. The halogenoalkanes are heated under reflux and then
treated with sodium or potassium hydroxide, resulting in propane.

,Condition (S): for this process, halogenoalkanes should be warmed or heated and in the
presence of sodium and or potassium hydroxide.

Nucleophilic substitution with hydroxide follows this mechanism:

2. ALCOHOL mainly an alcohol typically formed when one or more carbon atoms from
the hydroxyl group are bonded to a single alkyl group, as in ethanol and propanol. Each
primary alcohol has one OH group at the end of a hydrocarbon-based linear chain. Butyl
alcohol is a frequent term for a substance with the generic equation RCH2OH.
REACTIVITY 1:
If secondary alcohols are oxidised subsequently, they will create compounds like aldehydes
and others. It occurs if you use too much alcohol because there are just not enough
oxidising chemicals in the original procedure to proceed reach a certain point, and you'll be
capable of removing it as quickly as it forms since it doesn't have to be oxidised anymore. If
ethanol was employed as the acid, the result is ethanol, which would be an aldehyde.
REACTIVITY 2:
Carboxylic acids are generated by thoroughly oxidising the main alcohol; the same
circumstances are used to produce aldehyde and it is produced, but it is kept in the
combination. Following that, the alcohol must be warmed in a refluxing manner with an
abundance of an oxidant. The carboxyl group would be distilled out as quickly as the process
is finished. Basic alcohol is produced by oxidising a sodium or potassium dichromate (VI)
solutions with dilute acid or oxygen. Once ethanol is employed, the result is ethanoic acid,
which would be a carboxylic acid.

, Condition (S): You must employ an oxidising agent access and heat it all under flow before
allowing the oxidation of the alcohol to complete.

SECONDARY: An alcohol is formed whenever a carbon atom (or atoms) from the hydroxyl
group is connected to two alkyl groups. Thus, every secondary alcohol contains OH groups
at end of a stemmed chain made up entirely of hydrocarbons. R2CHOH is the general
formula, and sec-butyl alcohol is the common name.

REACTIVITY: If secondary alcohol is oxidised further, it will only produce ketones but
nothing else. Ketones are made via oxidation, which is a straightforward process that
doesn't necessitate any process conditions. During oxidation, the oxidising agent removes
two hydrogens from propan-2-ol, which is subsequently warmed in an acidified sodium or
potassium dichromate (VI) solution to produce propanone. Secondary alcohols, unlike
primary alcohols, utilise a solution of sodium or potassium dichromate (VI) that has been
acidified with dilute sulphuric acid as an oxidising agent.
