Question

(a) Give the molecular formula of one homologue of each of the following :
(i) $C_3{H}_6$ (ii) $C_2{H}_6$ (iii) $C_2{H}_2$
(b) What is the difference in the molecular mass of any two adjacent homologues?
(c) By how many carbon atoms and hydrogen atoms do any two adjacent homologues differ?

Answer 1

A) (i) $C_4{H}_8$
(ii) $C_3{H}_8$
(iii) $C_3{H}_4$


b)The difference between the molecular mass of two adjacent homologues is 14 a.m.u.


c) $C{H}_2$
