Answer:

The molecular formula of the compound : $C_4H_6O_2$

Explanation:

The empirical formula of the compound = $C_2H_3O$

The molecular formula of the compound = $C_{2n}H_{3n}O_n$

The equation used to calculate the valency is :

$n=\frac{\text{molecular mass}}{\text{empirical mass}}$

We are given:

Mass of molecular formula = 86 g/mol

Mass of empirical formula = 43 g/mol

Putting values in above equation, we get:

$n=\frac{86g/mol}{43g/mol}=2$

The molecular formula of the compound :

$C_{2\times 2}H_{3\times 2}O_2=C_4H_6O_2$

Which of the following is NOT soluble in water?

GrogVix [38]

C6H6 is the most insoluble in water as it is non polar in nature. HCL is highly soluble in water as it is an electrolyte. Kbr is also highly soluble in water. NaCl dissolves in water very quickly. CH3CH3OH is also totally soluble in water because of the Hydrogen bonding formation. It is a well known fact that the hydrocarbons do not easily mix with water. C6H6 being a strong hydrocarbon does not mix with water. So among NaCl, KBr, CH3CH3OH, HCl and C6H6, the hydrocarbon is the least soluble in water.
