Question

Match each of the following physical and chemical properties with cyclohexane, $C_6{H}_{12}$, or calcium nitrate, data-custom-editor="chemistry" $\mathrm{Ca}{\left({\mathrm{NO}}_3\right)}_2$:

a. melts at$500°C$

b. is insoluble in water

c. does not burn in air

d. is a liquid at room temperature

Short answer

(a) The compound that melts at $500°C$is calcium nitrate

(b) The compound that is insoluble in water is ${\mathrm{C}}_6{\mathrm{H}}_{12}$

(c) The compound that does not burn in the air is calcium nitrate

(d) The compound that is a liquid at room temperature is ${\mathrm{C}}_6{\mathrm{H}}_{12}$

Step-by-step solution

Part (a) Step1: Given information

We need to find that out of given compounds i.e. calcium nitrate and $cyclohexane$which melts at$500°C$

Part (a) Step 2: Explanation 

We know that

Calcium nitrate is an inorganic compound and $cyclohexane$is an organic compound.

And inorganic compounds have a relatively high melting point.

Therefore, The compound that melts at $500°C$is calcium nitrate

Part (b) Step1: Given information 

We need to find that out of given compounds i.e. calcium nitrate and $cyclohexane$which is insoluble in water

Part (b) Step 2: Explanation 

'We know that

Calcium nitrate is an inorganic compound and $cyclohexane$is an organic compound.

And organic compounds are relatively insoluble in water

Therefore, The compound that is insoluble in water is $cyclohexane$

Part (c) Step1: Given information 

We need to find that out of given compounds i.e. calcium nitrate and $cyclohexane$ which does not burn in the air

Part (c) Step 2: Explanation  

We know that

Calcium nitrate is an inorganic compound and $cyclohexane$is an organic compound.

And inorganic compounds do not burn in the air

Therefore, The compound that does not burn in the air is calcium nitrate

Part (d) Step1: Given information 

We need to find that out of given compounds i.e. calcium nitrate and $cyclohexane$ which is a liquid at room temperature

Part (d) Step 2: Explanation 

We know that

Calcium nitrate is an inorganic compound and $cyclohexane$is an organic compound.

Calcium nitrate is a solid. Most of the higher cycloalkanes are liquids at room temperature.

Therefore, The compound that is a liquid at room temperature is $cyclohexane$
