Question

A Which elements does a hydrocarbon contain?

b Calculate the empirical formulae of A and B.
c Calculate the molecular formulae of A and B.​

Answer 1

a. A hydrocarbon is any of a class of organic chemicals made up of only the elements carbon (C) and hydrogen (H). The carbon atoms join together to form the framework of the compound, and the hydrogen atoms attach to them in many different configurations.

Answer 2

hydrocarbon means that a compound only contains carbon and hydrogen contain together to form a chain.For example

methane-CH4 Main formula CnH2n+2

ethane- C2H6 methane empirical formula CH4

propane=C3H8 Methane molecular formula CH4

ethane empirical formula - C2H6

ethane molecular formula CH3-CH3 (C2H6)

propane empirical formula C3H8

propane molecular formula CH3-CH2-CH3 (C3H8)
