Is acetic acid more soluble in water or benzene?
Because of this, the extent of hydrogen bonding formation by benzoic acid in water is less than acetic acid. Hence, acetic acid is more soluble in water as compared to benzoic acid.
Which acetic acid is dissolved in benzene its molecular mass?
Ethanoic acid
The molecular mass of Acetic acid (Ethanoic acid) is 120g/mol when it is dissolved in Benzene. Note: Do not forget to mention the dimerization process occurring when acetic acid is dissolved in benzene.
Does acetic acid Dimerise in benzene?
Benzene is a non-polar solvent and acetic acid is a polar molecule. In benzene, two molecules of acetic acid form intermolecular H-bond and hence it exists as a dimer in Benzene.
How many molecules of acetic acid are dissolved in benzene?
The correct answer will be d) 120. Ethanoic acid (molar mass 60 g/mol) dimerises in benzene due to hydrogen bonding between its molecules and hence the molecular mass is higher than normal value.
Why acetic acid is soluble in water?
Explanation:It is because, Acetic acid contains only one carbon atom (which is present in the methyl group). So the compound faces no hindrance and is easily soluble in water. If the number of carbon atoms increases the compound becomes more bulky,then its solubility in water decreases.
Is acetic acid more polar than water?
Workup for Polar and Water-Soluble Solvents….Solvents and Polarity.
Solvent | Relative Polarity |
---|---|
acetic acid | 0.648 |
ethanol | 0.654 |
methanol | 0.762 |
ethylene glycol | 0.79 |
Why molecular mass of acetic acid in benzene determined by any Colligative property is higher than its actual molecular mass explain by deducing the relevant expression?
The molar mass of acetic acid in a solution of benzene solvent is greater than its formula molar mass because two CH3COOH molecules form a dimer (CH3COOH)2 in solution.
What happened in number of particles when acetic acid is dissolved in benzene?
Acetic acid undergoes dimerisation, when dissolved in benzene (as shown in figure) Molecular mass of acetic acid is found to be 120.
Why does acetic acid dissolve in nonpolar solvents?
Acetic acid can effectively “dimerize”, form a double structure held togeter very effectively by a geometrical arrangement that accommodates double hydrogen bonding. The resulting structure has no dipole moment. The “dimer” can then serve as a solvent in nonpolar solvents.
Why acetic acid does not act as an acid in benzene solution?
=> Acetic acid acts as acid in polar solution because polar solution helps acetic acid to ionise into acetate ion and proton… => Benzene is non-polar thus ionisation of acetic acid is not possible.
Why molecular weight of acetic acid and benzoic acid becomes double in benzene as solvent?
Answer: The observed molecular mass of benzoic acid in a non-polar solvent will be higher or doubled of its actual molecular weight. Because benzoic acid dimerizes ( undergoes association) in a non-polar solvent like benzene. Hence it forms a molecule of higher molecular mass.
What dissolves in acetic acid?
Solvents: Acetic acid is a hydrophilic solvent, similar to ethanol. It dissolves compounds such as oils, sulfur and iodine and mixes with water, chloroform and hexane.
