Question:
Empirical formula of a compound is $CH_2O$ and its molecular mass is $90$, the molecular formula of the compound is
Empirical formula of a compound is $CH_2O$ and its molecular mass is $90$, the molecular formula of the compound is
Updated On: Jul 12, 2022
- $C_3H_6O_3$
- $C_2H_4O_2$
- $C_6H_{12}O_6$
- $CH_2O$
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
The empirical formula of compound $= CH _{2} O$
Empirical formula mass
$=(1 \times 12)+(2 \times 1)+(1 \times 16)=30$
Molecular mass $=90$
$\therefore n=\frac{\text { Molecular mass }}{\text { Empirical mass }}=\frac{90}{30}=3$
and molecular formula $=3 \times CH _{2} O$
$= C _{3} H _{6} O _{3}$

- Given below are two statements :
Statement I : The boiling point of three isomeric pentanes follows the order
n-pentane > isopentane > neopentane
Statement II : When branching increases, the molecule attains a shape of sphere. This results in smaller surface area for contact, due to which the intermolecular forces between the spherical molecules are weak, thereby lowering the boiling point.
In the light of the above statements, choose the most appropriate answer from the options given below :- NEET (UG) - 2024

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
