Question

which is the only empirical formula :
i. C6H6
II. C2H4O2
III. C6H12O6
IVC12H22O11

Answer 1

Explanation:

Empirical formula → A formula giving the proportions of the elements present in a compound but not the actual numbers or arrangement of atoms.

In other words, empirical formula can be defined as the simplest form of molecular formula.

(A) Benzene (C

6

H

6

)-

Ratio of atoms-

C:H=6:6=1:1

∴ Empirical formula will be →CH

(B) Glucose (C

6

H

12

O

6

)-

Ratio of atoms-

C:H:O=6:12:6=1:2:1

∴ Empirical formula will be →CH

2

O

(C) Acetylene (C

2

H

2

)-

Ratio of atoms-

C:H=2:2=1:1

∴ Empirical formula will be →CH

(A) Hydrogen per oxide (H

2

O

2

)-

Ratio of atoms-

H:O=2:2=1:1

∴ Empirical formula will be →HO
