Question

The table shows the chemical formulas for four substances which substances have the same number of carbon atoms

Answer 1

Substance 1 and 3.

Step-by-step explanation:

The following data were obtained from the question:

Substance >>>>> chemical formula

1 >>>>>>>>>>>>>> C2H6O

2 >>>>>>>>>>>>>> C8H18

3 >>>>>>>>>>>>>> CH3CH2Br

4 >>>>>>>>>>>>>> C4H10O

Next, we shall determine the number of carbon in each substance as follow:

Substance 1 (C2H6O):

Number of carbon atom = 2

Substance 2 (C8H18)

Number of carbon atom = 8

Substance 3 (CH3CH2Br)

Number of carbon atom = 1 + 1 = 2

Substance 4 (C4H10O)

Number of carbon atom = 4

From the above illustrations,

Substance 1 and 3 has the same number of carbon atom
