Question

Acetylene and benzene both have the empirical formula CH. The empirical formula of acetylene &benzenes are26&78 respectively.
The molecular formula will be
a)C6H6,C2H2
b) C7H7,C2H2
c) C3H6,C4H4
d) C6H6,C6H6.​

Answer 1

Answer:

your answer is acetylene C2H2 and benzene C6H6

Answer 2

Answer:

your options are wrong, it will be acetylene-C2H2

benzene-C6H6

Explanation:

since emperical formula is CH

let no. of atoms of H =no. of atoms of C=x

12x + 1x =26

13x=26

x=2

therefore for acetylene molecular formula is C2H2

smilarly for benzene
