In HS-,I-,R–NH2, NH3 order of proton excepting tendency will be :-
In HS-,I-,R–NH2, NH3 order of proton excepting tendency will be :-
I- > NH3 > R–NH2 > HS-
NH3 > R-NH2 > HS- > I-
RNH2 > NH3 > HS-> I-
HS-> RNH2 > NH3 > I-
The Correct Option is C
Solution and Explanation
The correct option is (C): RNH2 > NH3 > HS-> I-
The order of proton-accepting tendencies is as follows: R−NH2 > NH3 > HS- > I-.
The reduced proton-accepting ability of the iodide ion is attributed to its larger size, which leads to a lower charge density due to the negative charge being distributed over a larger area. Conversely, alkylamines exhibit a greater propensity to accept protons compared to ammonia, owing to the +I (inductive effect) influence of the alkyl group.

Concepts Used:
Organic Chemistry – Some Basic Principles and Techniques - Reaction Mechanism
SN1 Reaction Mechanism:
SN1 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
