Question

Which pair of formulas represents the same compound? ch3ch2cho; ch3ch2cooh ch3coh(ch32; (ch3 3coh c2h5oh; ch3och3 (ch32co; ch3och3?

Answer 1

Answer: The correct answers are $CH_3COH(CH_3)_2;(CH_3)_3COH$ and $C_2H_5OH;CH_3OCH_3$

Explanation:

The formulas having same compound will have same number of individual atoms.

From the given options:

• Option 1: $CH_3CH_2CHO;CH_3CH_2COOH$

In compound 1:

Number of carbon atoms = 3

Number of hydrogen atoms = 6

Number of oxygen atoms = 1

In compound 2:

Number of carbon atoms = 3

Number of hydrogen atoms = 6

Number of oxygen atoms = 2

As, number of oxygen atoms in both the compounds are not same. Thus, these two do not represent same compounds.

• Option 2: $CH_3COH(CH_3)_2;(CH_3)_3COH$

In compound 1:

Number of carbon atoms = 4

Number of hydrogen atoms = 10

Number of oxygen atoms = 1

In compound 2:

Number of carbon atoms = 4

Number of hydrogen atoms = 10

Number of oxygen atoms = 1

Here, all the atoms of every element is same. Thus, these two compounds represent same compound.

• Option 3: $C_2H_5OH;CH_3OCH_3$

In compound 1:

Number of carbon atoms = 2

Number of hydrogen atoms = 6

Number of oxygen atoms = 1

In compound 2:

Number of carbon atoms = 2

Number of hydrogen atoms = 6

Number of oxygen atoms = 1

Here, all the atoms of every element is same. Thus, these two compounds represent same compound.

• Option 4: $(CH_3)_2CO;CH_3OCH_3$

In compound 1:

Number of carbon atoms = 3

Number of hydrogen atoms = 6

Number of oxygen atoms = 1

In compound 2:

Number of carbon atoms = 2

Number of hydrogen atoms = 6

Number of oxygen atoms = 1

As, number of carbon atoms in both the compounds are not same. Thus, these two do not represent same compounds.

Hence, the pairs which represent same compounds are $CH_3COH(CH_3)_2;(CH_3)_3COH$ and $C_2H_5OH;CH_3OCH_3$

Answer 2

The pair of formulas which represents the same compounds are CH₃COH(CH₃)₂, (CH₃)₃COOH and C₂H₅OH, CH₃OCH₃.

What are compounds?

Compounds are those substances which are formed by the mixture of different kind of atoms.

• CH₃CH₂CHO & CH₃CH₂COOH

In the above given formulas of compound both are not same compound as the number of oxygen atom is different in that.

• CH₃COH(CH₃)₂ & (CH₃)₃COOH

Above given formulas represent the same compounds as in that all atoms are present in same quantity.

• C₂H₅OH & CH₃OCH₃

In the above two given formulas all elements are present in equal amount so that they represent the same compound.

• (CH₃)₂CO & CH₃OCH₃

In the above two formulas number of carbon atoms are not equal in two compound so that they will not represent the same compound.

Hence CH₃COH(CH₃)₂, (CH₃)₃COOH and C₂H₅OH, CH₃OCH₃ represent same compounds.
