carboxylic acids
diols
dialdehydes

Hide Solution

Verified By Collegedunia

The Correct Option is B

Solution and Explanation

$ {{C}_{n}}{{H}_{2n}}{{O}_{2}} $ is the general formula for open chain carboxylic acid and ester, e.g., if $ n=3\Rightarrow {{C}_{3}}{{H}_{6}}{{O}_{2}} $ Acid- $ C{{H}_{3}}C{{H}_{2}}COOH $ Ester- $ C{{H}_{3}}COOC{{H}_{3}} $

Organic Chemistry – Some Basic Principles and Techniques - Reaction Mechanism

SN1 Reaction Mechanism:

S_N¹ reaction mechanism takes place by following three steps –

Formation of carbocation
Attack of nucleophile
Deprotonation

SN2 Reaction Mechanism:

The SN2 reaction mechanism involves the nucleophilic substitution reaction of the leaving group (which generally consists of halide groups or other electron-withdrawing groups) with a nucleophile in a given organic compound.

Electrophilic Aromatic Substitution Reaction Mechanism:

The mechanism of an electrophilic aromatic substitution reaction contains three main components which are:

A new sigma bond from C=C is formed during the reaction in the arene nucleophile.
Due to the breaking of the C-H sigma bond, a proton is removed.
The C=C bond is reformed and it restores the aromaticity of the compound.

Electrophilic Substitution Reaction Mechanism:

The electrophilic substitution reaction mechanism is composed of three steps, which will be discussed more below.

Electrophile Generation
Carbocation Formation
Proton Removal
