Question

Give the Empirical formula of :

i) C6H6 ii) C6H8O3 iii) C2H2 iv) CH3COOH

v) C6H12O6 vi) C8H604

​

Answer 1

Explanation:

(I) Ratio of atoms-

C:H=6:6=1:1

∴ Empirical formula will be →CH.

(ii) Ratio of atoms-

C:H:O=6:8:3

∴ Empirical formula will be →C6H8O3.

(iii) Ratio of atoms-

C:H=2:2=1:1

∴ Empirical formula will be →CH.

(iv) Ratio of atoms-

CH:COOH=3:1=3:1

∴ Empirical formula will be →CH3COOH.

(v)Ratio of atoms-

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

∴ Empirical formula will be →CH2O.

(vi) Ratio of atoms-

C:H:O=8:6:4=4:3:2

∴ Empirical formula will be →C4H3O2.
